For people's consideration. Restore the .11 behaviour of not initialising sound if music is turned off. Reason. I still get 100% CPU useage in frontend due to sucky sound daemon setups *cough*pulseaudio*cough* so this offers an easy workaround for people (turn off music). Disadvantage, this removes Smaxx' code to disable sound-related buttons on failure to init sound.
### SuperTux - Removed unused vorbisenc library
# - Try to find the OggVorbis libraries
# Once done this will define
#
# OGGVORBIS_FOUND - system has OggVorbis
# OGGVORBIS_VERSION - set either to 1 or 2
# OGGVORBIS_INCLUDE_DIR - the OggVorbis include directory
# OGGVORBIS_LIBRARIES - The libraries needed to use OggVorbis
# OGG_LIBRARY - The Ogg library
# VORBIS_LIBRARY - The Vorbis library
# VORBISFILE_LIBRARY - The VorbisFile library
