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.

+DescribeTable describes a table-driven test.
+
+For example:
+
+    DescribeTable("a simple table",
+        func(x int, y int, expected bool) {
+            Ω(x > y).Should(Equal(expected))

+    )
+
+The first argument to `DescribeTable` is a string description.
+The second argument is a function that will be run for each table entry.  Your assertions go here - the function is equivalent to a Ginkgo It.
+The subsequent arguments must be of type `TableEntry`.  We recommend using the `Entry` convenience constructors.
+
+The `Entry` constructor takes a string description followed by an arbitrary set of parameters.  These parameters are passed into your function.
+
+Under the hood, `DescribeTable` simply generates a new Ginkgo `Describe`.  Each `Entry` is turned into an `It` within the `Describe`.
+
+It's important to understand that the `Describe`s and `It`s are generated at evaluation time (i.e. when Ginkgo constructs the tree of tests and before the tests run).
+
+Individual Entries can be focused (with FEntry) or marked pending (with PEntry or XEntry).  In addition, the entire table can be focused or marked pending with FDescribeTable and PDescribeTable/XDescribeTable.
