new clones
Atom (bootleg of Bombjack Twin) [f205v] (not working)

new NOT WORKING
Sea Battle [ANY]
new NOT WORKING
Midcoin Juke Box 24CD [f205v]
Various CD-ROM / CHDMAN improvements: [R. Belmont]
- Correct import/export of bin/cue images in which the pregap sectors are present.
- Normalized TOC handling; the start of a track is always the first pregap sector.
- Finally allows reading and CDDA playing pregap sectors.  Works even if the pregap sectors are not present in the file.

nw part: Existing CHDs should work (or not) as before - previously non-working ones that were broken due to disc geometry should work if regenerated from source.

I tested this on several known-touchy cases (including Saturn Black/Matrix Reprint cinemas and PCE-CD Prince of Persia) but there are likely others.

Drivers that tried to fake around the previous lack of pregap reading on CDDA may need some adjustment.
