BattleRPG for UT3 construction

Working on the first BattleRPG prototype now.

Working:
* Scoreboard capable of showing things like RPG levels (skeleton finished, content needs work), autodownloading tested to work properly with patch 1 beta 4
* HUD capable of showing things like level, xp and mana (skeleton finished, content needs work)
* Network efficient multiple inheritance emulation to add RPG specific data to PRI's (player replication info) for all gametypes, fully tested on dedicated server to work

To do:
* Persistant server side storage of level and xp
* Content of scoreboard and hud
* Mana, level and xp calculations
* Some simple form of rewards for having mana and levels (probably some BattleMOD stuff)

The BattleRPG P1 prototype will be fully functional and operational. It is however a first step. Future prototypes will add things like magic weapons, magic vehicles, artifacts, abilities and ability management. Once those are implemented it will no longer be a prototype and become BattleRPG V1. All versions will be GPL V3 and include full source code.
