ansuz 1f24d7126c big ugly commit that will be really hard to audit
This changeset applies new styles to the poll.

it also uses the new asynchronous wrappers around the localStorage api.
this is necessary because we're migrating to a storage system that will
use an async api.

The changes to the poll just happened to coincide with the async stuff.

My apologies to anyone who wants to read this whole thing
