[all code changes by Glenn Maynard]
--------
cleanup
small amount of work on guitar-five (still incomplete)
add more commented out stuff for replay data playback
debug trace combo in order to find out issues with smo-ssc
added old packet names as comments in NetworkSyncManager.h
[Course.cpp] HasTimedMods() now actually checks for timed mods (technically non-global) instead of being a clone of HasMods()
[Player.cpp] add MAX_HOLD_LIFE/[Player] MaxHoldLife metric
[ScreenGameplay] looking into places to put loading of replay data, perhaps?
[elsewhere] lots of cleanup, and I'm sure there's lots more to be done.
add a todo to ProductivityHelpers.
