Event Addon

1. Made it super easy to add your own code for events (go to ea_server.lua and put your custom code in there)
2. Made the embankment event an auto event
3. Fixed bug where !startevent would break if an event is already running
4. Perfected system where people get removed from event
5. Fixed hot joining the event
6. Fixed exit event button bugging peoples load outs
7. Refined all the events to hopefully be bug-free

Sorry for the multiple updates in the last 2 days, there shouldn't be anymore for at least a week and then a feature rich update :)
