New Feature: Facebook Integration

[RobinHood]

I've now added Facebook integration so you can log in with your Facebook account. This won't really affect most of our current users as we already have an account, however if you want you can link your current forum account with your facebook acccount and then if you do happen to click any official facebook like or recommend buttons on the site it will link to your profile (this doesn't apply to the like buttons at the bottom of every post).
