Added enabling character-ROM

Now I added the CHAREN signal of the port 0001 from the 6510 to enabling the character ROM.
PAC-MAN and Pipes uses this to read the letters and numbers from the built-in-font to save memory in the cartridge-rom.
I use now 2 GAL22V10 because I need all the outputs.
The CHAREN is detected in the second GAL and stored in a D-Latch like LORAM/HIRAM.
PAC-MAN uses multicolor-textmode - I have to add it in the Xmega now :-)
Gameplay-Video - now with Joystick :-) but without sprites ;-(   PAC-MAN-gameplay

Pipes uses CHAREN too - and works now perfectly!
