dimok321 fa11a745d6 A lot of changes with this rev
*Rewrote the whole Settings.cpp into 11 classes. Each settings menu has it's own class now
*Reworked the whole sound system. Supported formats AIF/MP3/OGG/BNS/WAV now with no file size limit (streaming).
*Changed button click/over sounds to wav from raw pcm
*Lot's of bug fixes
