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processor.h is obsolete, thus removed.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)
Wrapped gSettings and the global objects returned by Settings::get() and
Globals::get() in AIThreadSafe, forcing thread-safe access.
This solves the problem of possible corruption of the various LevelMap's
in LLError::Settings due to thread unsafe accesses.
