Atari800/Atari5200

• Support for VBXE (Wojciech Mostowski).

• Support for CAS files and Carts, many fixes (Wojciech Mostowski).

• Artifacting module for 5200 core from the 800 one (Wojciech Mostowski).

There is a big change in internal core structure. Some functionality has been moved to Main, so this version will work only with new just released Main. Older Main version won't work. Older versions of Atari800/5200 won't work with new Main either. So, make sure both main and core are updated. Also update boot[0-3].rom and *.act files!
