Pulled LLEventTimer out of lltimer.h/cpp and into lleventtimer.h/cpp

LLInstanceTracker added to llcommon (pulled from llui in v2 for usage elsewhere)
LLEventTimer now using LLInstanceTracker
Updated LLLiveAppConfig (Though it appears unused, really)
processor.h is obsolete, thus removed. (llprocessor.h replaces it)
