old lua test stuff by hawkear removed or commented

new function: Party.SetWinner sets winner of current round
new unit ULuaUtils w/ some functions that are or may become useful
moved Lua_ClearStack and Lua_ToBinInt to ULuaUtils
added first hooks (have a look at hooks.txt in game/plugins until documentation is finished)
lua module for TextGl written and finished
lua testfile (game/scripts/main.lua) ported to new interface, see game/plugins/LuaTest.usdx
