MCMEPVP_Core - work so far
- handles the core functionality for pvp games
- gamemodes are to be made as seperate plugins which will be loaded as 'modules' by the Core plugin
    - should allow for more complex game-modes with specifically-made, more efficient listeners etc

Currently Implemented:
- pvpPlayer wrapper
- map loading/saving + commands
- user /pvp commands (no mod/admin cmds yet)
- can load/unload module plugins from the 'MCMEPVP_Core/modules' folder
    - modules must be in the format of 'MCMEPVP_GameType.jar'
