Added support for an event calendar

[KrAzE]

Despite the fact that I cant spell the word calendar on a good day, I have enabled its support for everyone. Instead of adding to the forum, you can click the calendar link uptop and add an event by either clicking the day you want to add it, or by clicking post event at the bottom of the large calendar.

If you accidently made a event post before the calander, you can correct this at the bottom of your topic.. theres a link to calendar option!
