Addition to m68k Amiga

Additional try on my real Amiga1200 which does not have a gfx-card. So only AGA with 64 colors on the workbench. Also the calls to set a color on a rastport using 24bit values is not available so one have to use pens. I did already some changes in the code to use Pens on a real Amiga, and disabled the cybergraphics calls if no cybergraphics.library is available. EdiSyn sadly crash, maybe I missed one cgfx call, but the FPCMines seems to work, ok needs longt time to start and slow drawing but it works. It’s even playable in a reasonable Speed.
