Finish off poll functionality started by jimrandomh

[GoogleCodeExporter]

In the [polls branch](https://github.com/tricycle/lesswrong/tree/polls) there 
is an implementation of polling functionality contributed by jimrandomh. 
There's a bit of work left to improve the styling and make it more robust. This 
is includes but is not limited to:

* Handle malformed polls, `[poll:asdf]`.
* Handle invalid input such as entering a letter as the response to a 'number' 
poll.
* Determine a way to escape a poll. Currently it isn't possible to enter the 
poll syntax and have it display.
* Show feedback when submitting a response to a poll.

Also needed:
* documentation for the users, probably under the "Show help" button
* make sure people can't vote multiple times

Note that "documentation for the users, probably under the "Show help" button" 
was included in the original fork but I removed it during the merge to master. 
This is because since the original fork was made the content shown by the Show 
Help button is now pulled from wiki.lesswrong.com. See this commit for the help 
content:

Required functionalillty (from #320):
An "integrated" solution more like a typical poll that allow you to insert a 
poll within a comment, or create a "special" comment that is just a poll (e.g. 
poll title/question, single-select or multi-select, and the options to choose 
from). There could then be a "Show results" link below the poll that would clip 
from the poll form to the results view, and "Hide results" would flip back to 
showing the poll. Votes on polls would always be tied to each user account, so 
users could go back later and change their vote if they desired. Moreover, 
you'd need to have 20 karma in order to vote on polls. No karma goes to the 
creator of the poll from votes.

Graphic design will be supplied, tightening up the design of the current 
implementation.
