Improvements to Noraut Poker driver...

Browse Source 
* Routed the whole video RAM access through PPI-2.
   (bypassed the handshake lines for now).
 * Merged back the noraut machine drivers after the 3rd PPI connection.
 * Added Low Level Hopper manual input.
 * Added a new machine driver for extended hardware.
   It has 2 jumpers that cut the a14 and a15 addressing lines.

TODO:
- Analize the third 8255 at 0xc0-0xc3 (full bidirectional port w/hshk lines)
- Video RAM (through 3rd PPI?).
- Analize PPI-2 at 0xc0-0xc3. OBF handshake line (PC7) doesn't seems to work properly.
- Find if wide chars are hardcoded or tied to a bit.
- Discrete sound.
- Save support.
