This breaks 3d modes and serve very little use in the real world
renderers: rename stereo 3d mode flag to more distinct name
added: support SBS and TAB display of xbmc gui
dvdplayer: pass stereo_mode to renderers and select what to render

Conflicts:
	xbmc/cores/dvdplayer/DVDStreamInfo.cpp
	xbmc/cores/dvdplayer/DVDStreamInfo.h
d3d: support anaglyph stereo rendering
gl: support anaglyph and interlaced stereo rendering
