Beta 2:

* CD32/CDTV image mounting broke in b1 (can still be broken in some situations)
* new audio state machine emulation froze in some situations
* re-added "too fast CPU" hack that fixes missing sounds with sound routines that use CPU loops in DMA waits (also needed in 68020 "CE" mode because short loops are currently too fast)
* automatic audio switching detected idle audio when playing long samples
* CD32 statefile restore ignored possible CD image file path in statefile
* CDTV CD led flicker was practically non-existing when reading data
* (I also noticed CDTV statefile support is still missing..)
* old CD audio timecode relative track position bug fixed (CDTV audio CD player slow time display)
* built-in image mounter cd audio timecode relative track position had 2 second offset
* real cd audio cd playback asked for exclusive CD access when shared also works fine
* do not parse mounted images (cue files) twice when booting in CD32 or CDTV mode
* path update in b1 broke D3D related paths
* CDTV processing thread stalled if no drive was detected when exiting
