Poll feature

A poll feature for the sim has been implemented, which allows rooms to run their own polls. They are a nice built-in alternative for the many straw polls ran by various rooms. These polls are limited to one poll at a time per room, and display in the room when they're created, ended, or when someone joins the room. We're still in early development with this feature, so we'll appreciate any suggestions done to make things better. Enjoy!
