Use Go 1.5 vendoring instead of Godeps

Change made by:

- running "gvt fetch" on each of the packages mentioned in
  Godeps/Godeps.json
- `rm -rf Godeps`
- tweaking the build scripts to not mention Godeps
- tweaking the build scripts to test `./lib/...`, `./cmd/...` explicitly
  (to avoid testing vendor)
- tweaking the build scripts to not juggle GOPATH for Godeps and instead
  set GO15VENDOREXPERIMENT.

This also results in some updated packages at the same time I bet.

Building with Go 1.3 and 1.4 still *works* but won't use our vendored
dependencies - the user needs to have the actual packages in their
GOPATH then, which they'll get with a normal "go get". Building with Go
1.6+ will get our vendored dependencies by default even when not using
our build script, which is nice.

By doing this we gain some freedom in that we can pick and choose
manually what to include in vendor, as it's not based on just dependency
analysis of our own code. This is also a risk as we might pick up
dependencies we are unaware of, as the build may work locally with those
packages present in GOPATH. On the other hand the build server will
detect this as it has no packages in it's GOPATH beyond what is included
in the repo.

Recommended tool to manage dependencies is github.com/FiloSottile/gvt.

+## HEAD
+
+Improvements:
+
+- Added `BeSent` which attempts to send a value down a channel and fails if the attempt blocks.  Can be paired with `Eventually` to safely send a value down a channel with a timeout.
+- `Ω`, `Expect`, `Eventually`, and `Consistently` now immediately `panic` if there is no registered fail handler.  This is always a mistake that can hide failing tests.
+- `Receive()` no longer errors when passed a closed channel, it's perfectly fine to attempt to read from a closed channel so Ω(c).Should(Receive()) always fails and Ω(c).ShoudlNot(Receive()) always passes with a closed channel.
+- Added `HavePrefix` and `HaveSuffix` matchers.
+- `ghttp` can now handle concurrent requests.
+- Added `Succeed` which allows one to write `Ω(MyFunction()).Should(Succeed())`.
+- Improved `ghttp`'s behavior around failing assertions and panics:
+    - If a registered handler makes a failing assertion `ghttp` will return `500`.
+    - If a registered handler panics, `ghttp` will return `500` *and* fail the test.  This is new behavior that may cause existing code to break.  This code is almost certainly incorrect and creating a false positive.
+- `ghttp` servers can take an `io.Writer`.  `ghttp` will write a line to the writer when each request arrives.
+- Added `WithTransform` matcher to allow munging input data before feeding into the relevant matcher
+- Added boolean `And`, `Or`, and `Not` matchers to allow creating composite matchers
+
+Bug Fixes:
+- gexec: `session.Wait` now uses `EventuallyWithOffset` to get the right line number in the failure.
+- `ContainElement` no longer bails if a passed-in matcher errors.
+
+## 1.0 (8/2/2014)
+
+No changes. Dropping "beta" from the version number.
+
+## 1.0.0-beta (7/8/2014)
+Breaking Changes:
+
+- Changed OmegaMatcher interface.  Instead of having `Match` return failure messages, two new methods `FailureMessage` and `NegatedFailureMessage` are called instead.
+- Moved and renamed OmegaFailHandler to types.GomegaFailHandler and OmegaMatcher to types.GomegaMatcher.  Any references to OmegaMatcher in any custom matchers will need to be changed to point to types.GomegaMatcher
+
+New Test-Support Features:
+
+- `ghttp`: supports testing http clients
+    - Provides a flexible fake http server
+    - Provides a collection of chainable http handlers that perform assertions.
+- `gbytes`: supports making ordered assertions against streams of data
+    - Provides a `gbytes.Buffer`
+    - Provides a `Say` matcher to perform ordered assertions against output data
+- `gexec`: supports testing external processes
+    - Provides support for building Go binaries
+    - Wraps and starts `exec.Cmd` commands
+    - Makes it easy to assert against stdout and stderr
+    - Makes it easy to send signals and wait for processes to exit
+    - Provides an `Exit` matcher to assert against exit code.
+
+DSL Changes:
+
+- `Eventually` and `Consistently` can accept `time.Duration` interval and polling inputs.
+- The default timeouts for `Eventually` and `Consistently` are now configurable.
+
+New Matchers:
+
+- `ConsistOf`: order-independent assertion against the elements of an array/slice or keys of a map.
+- `BeTemporally`: like `BeNumerically` but for `time.Time`
+- `HaveKeyWithValue`: asserts a map has a given key with the given value.
+
+Updated Matchers:
+
+- `Receive` matcher can take a matcher as an argument and passes only if the channel under test receives an objet that satisfies the passed-in matcher.
+- Matchers that implement `MatchMayChangeInTheFuture(actual interface{}) bool` can inform `Eventually` and/or `Consistently` when a match has no chance of changing status in the future.  For example, `Receive` returns `false` when a channel is closed.
+
+Misc:
+
+- Start using semantic versioning
+- Start maintaining changelog
+
+Major refactor:
+
+- Pull out Gomega's internal to `internal`

+Package ghttp supports testing HTTP clients by providing a test server (simply a thin wrapper around httptest's server) that supports
+registering multiple handlers.  Incoming requests are not routed between the different handlers
+- rather it is merely the order of the handlers that matters.  The first request is handled by the first
+registered handler, the second request by the second handler, etc.
+
+The intent here is to have each handler *verify* that the incoming request is valid.  To accomplish, ghttp
+also provides a collection of bite-size handlers that each perform one aspect of request verification.  These can
+be composed together and registered with a ghttp server.  The result is an expressive language for describing
+the requests generated by the client under test.
+
+Here's a simple example, note that the server handler is only defined in one BeforeEach and then modified, as required, by the nested BeforeEaches.
