WINTERMUTE: Do syncSoundSettings on initialization of sound manager, so that sound settings are actually applied on launch
FULLPIPE: Implement Bitmap::flipVertical()
FULLPIPE: Add 16bit/RGB backend support dependancy.
ALL: Remove support for MSVC8 and older

MSVC8 gives various compile error relating to templates that were changed
back in 2008, leading me to belive that no one is using it, and that there
is not point adding work arounds for a 9 year old compiler no one uses.
