Subject: Streamline fmodstudio/openal targets: - Targets now define the
 appropriate c++ defines, no more hand magic needed for llstartup.cpp - Switch
 cmakeflage to USE_xxx rather than xxx as it was before. I personally find the
 USE_X notion more intuitive and it follows how KDU is used. - To be backward
 compatible OPENAL/FMODSTUDIO flag will be mapped to USE_OPENAL/USE_FMODSTUDIO
