Phew, next beta already:

* MP3/FLAC background decompression, no more delayed CDA startup if audio file decompression takes more than 2 seconds
* implemented "delayed decompression" zfile open flag, currently only zip backend supports it and it is only enabled when using CD images. Most zipped CD images with big audio files start almost instantly now
* potential memory corruption crash in zfile_fclose() if file had parent file(s)
* zero length disk DMA (used by some copy protections) never finished, broke in b1
* fixed extra space characters in favorite menu items
* pause uaescsi.device CDA when emulation is paused or GUI is open
* uaescsi.device CDA lights green on screen CD led
* cue/bin audio tracks were completely silent (cue/wav worked)
* on the fly image switching didnīt send uaescsi.device change interrupts correctly if CDFS polling flag was disabled (empty drive without diskchange command)
* new dynamic hardfiles have .vhd extension instead of .hdf
