Beta 20: (nearly there?)

- Fixed DirectDraw on screen led status bar surface allocation error when switching modes in some situations.
- A3000 quickstart CIA mapping fixed (no mirrors, can´t enable both CIAs at the same time, only original Gary does this) and 0xc0-0xcf added (same as A4000) Only affects very badly behaving programs, programs that most likely wouldn´t run on A3000 or A4000, with or without this change.
- Do not fully recalculate display parameters if only long/short field state changes.
- Lacenon-lace mode switch scanline flashing effect hopefully fixed (may also break something else..)
- Overlay graphics Direct3D mode should have more correct positioning again (still not exactly right)
- Z3 board <16M RAM size autoconfig data makes more sense.
- Upper half of 8M RTG Z2 board was overridden by Gayle PCMCIA address space if enabled.
- Windows 8 Consumer Preview tested, didn´t notice any problems. WARNING: No Windows 8 discussion here!

I think I´ll leave sound buffer adjustments for later (after 2.4.0). It would take at least a month or more to get back to stable state and this update would only affect low sound buffer vsync modes.
