Test7800 v0.7.5

Test7800 v0.7.5 is released. Test7800 is an experimental emulator for the Atari 7800. It's not complete and is missing some important features but it plays many of the 7800 ROM files that are available. It supports a78 files and will emulate regular "flat" ROM files and also "supergame" ROM files. It does not yet emulate the POKEY chip and similar hardware. The 6502, TIA and RIOT emulation is taken from Gopher2600 and is therefore well tested. The implemenation of the MARIA is new to this project.
