Added rudimentary voting

[swilliams]

Hey man,

I got some basic voting in. The UI kind of sucks: I stole reddit's up arrow, and couldn't quite figure out how to make it work with your css, but the functionality is there. It simply checks IP address and will only let you vote once per suggestion. Feel free to change it around and outright reject altogether :).

Is it just me or does the sorting for popularity not work? I'm working on a solution right now to test this out, but it threw errors at me when I tried it.

Forgot about that when I refactored the Votes into a separate class. I'll take care of it tonight. Poop.
