Add a background highlight to vote count button if currently
logged in user votes on that option.
Tweaked by tabbott to use better variable names and Rishi for better
styling.
We had initially designed the poll widget like a blog
post with comments beneath it but it makes more sense
to think of it as just a simple poll with options.
NOTE: If you revert this commit, you want to revert
the immediately prior commit as well. The history
is that Ishan made some improvements to the widget,
but there were some minor bugs. I decided not
to squash the commits together so that the git
history is clear who did what. (In particular, I
want questions about the JS code to come to me if
somebody does `git blame`.)
Anyway...
This is a fairly significant rewrite of the polling
widget, where I clean up the overall structure of
the code (including things from before the prior
fix) and try to polish the prior commit a bit as
well.
There are a few new features:
* We tell "other" users to wait for the poll
to start (if there's no question yet).
* We tip the author to say "/poll foo" (as
needed).
* We add edit controls for the question.
* We don't allow new choices until there's
a question.
