New Posting Features - Hambil's Weighted Polls

Allows for different usergroups to have different 'weights' when voting in a poll. A usergroup with a weight of 5 would have 5 times the voting power of a usergroup with a weight of 1. Weighted Polls are optional, and in addition to regular polls.

Based on Hambil's first Weighted Polls engine which is now obsolete, this one is way more efficient, have less queries, and is easier to manage in permissions.

A good usage for this feature is when you have Elections, Votes on Who's Hot or Not, etc... You then give your more representative members a higher weight in polls.
