Allow 64k carts to work. Switch keyboard to PS2 port 2.

Changed mem addresses

Switched DAC

Added multiple build types

Added 32 bit sram access to make zpu work

sram works, boots, keyboard works

Fixed PLL to more appropriate for PAL/NTSC with he 32MHz input clock. Should work now, although no ZPU yet!

replacing with pal/ntsc plls of correct input frequency

First cut of papilio duo support. NB: This does not work yet, notably PLL needs changing. Then sram needs wiring up to allow zpu to run.
