Melee - Outpost v2

Melee Gamemode, currently only 8 spawns but should be good for between 6-16 players, any less than that and it might feel to be more spread out.

Updated the map in an attempt to streamline gameplay, removed water near the spawns that was causing issue and unbalancing spawns. I've added in the power tracks to speed up movement around the outer courtyard.

This is still pretty much my first attempt with mapping for a mania game but please do let me know if you've seen any problems or issues that could use some attention or otherwise fixing.
