Changed underlying datatype for 'Velocity' to sbyte instead of byte to allow negative values.

If this causes anyone issues, please email me [email@example.com] and I can fix the file and send it back too you.
Added Drop Down List above PropertyGrid for selecting of Maze Objects by name

All space scenes are now skipped in both Attract mode and gameplay mode. This keeps you from wasting precious rex's in space.
0.2.0.0 - 5/31/2009
Turned Mazes back on (accidentially disabled buttons in last release) - Thanks Ataricade!
Fixed Issue with only Maze Type A being emulated, you may now emulate all Maze types. There are probably still some oddities in non-Type A mazes due to assumptions in the original code about attract mode always running level 1.
Added checking for MAME running with compressed ROM archives rather than folder + files. If the MAME roms folder contains a .zip file that matches the driver being used, the user will be given a warning and the emulation will not continue until MAME is reconfigured to not use compressed ROM's. Thanks Lee Bender!
Fixed 'Phantom' perkoid that was always present way up in upper left corner of all mazes due to ROM dumping error.
