More improvements to Noraut Poker driver [Roberto Fresca, Alan Griffin]

Browse Source 
* Executed a trojan on 2 noraut systems to confirm the way 16x32 tiles are decoded.
 * Fixed the x-offset for 32x32 tiles lines.
 * Fixed the screen aspect and visible area.
 * Confirmed correct colors. No bipolar PROM involved.
 * Added Noraut Joker Poker hardware and PCB layouts.
 * Documented the discrete audio circuitry. Added a full diagram.

- Added partial DIP switches to norautrh.
- Added more technical notes.
[2009-08-23]
[2009-08-23/26]
- Added a default NVRAM to Noraut Joker Poker to bypass the 'F U' screen.
This is due to the phisical keyboard limitation when needs to enter
4 simultaneous inputs.
- Executed a trojan on 2 noraut systems to confirm the way 16x32 tiles are decoded.
- Fixed the x-offset for 32x32 tiles lines.
- Fixed the screen aspect and visible area.
- Confirmed correct colors. No bipolar PROM involved.

The strange issue is that some sets just configure the PPI to mixed mode2 and mode0 input.
it means that port A should be bidirectional and port B just as input. (port C as hshk regs).
So... it doesn't match the addressing through c1.
