Sega Improvements [Aaron Giles]

Sega System 16A:

it's really right yet
* reintroduced tilemap/text priorities
* corrected Z80 clock speed
* incorporated Brian Troha's updated DIPs
* minor cleanups

Sega System 16B:
* fixed ROM bank mapping so it doesn't fall through to unmapped handlers
* incorporatedBrian Troha's updated DIPs
* minor cleanups
* fixed column scroll after talking to Charles about how it
works

Sega System 18:
* fixed ROM bank mapping so it doesn't fall through to unmapped handlers
(fixes Shadow Dancer crash)
* expanded memory mapping code so it works from the 8751 as well as the
68000
* hooked up the 8751 in mwalk/mwalka/mwalkb -- these all work now
* removed coin lockouts as they were breaking several games' coin inputs
* hooked up Laser Ghost controls and added crosshair drawing (not 100% yet,
feel free to tweak)
* hooked up Where's Wally controls
* fixed astorm's Player 3 controls
* cleaned up ddcrew's inputs
* fixed sound ROM loading in astorma/astorm2p/mwalk*
* incorporated Brian Troha's updated DIPs
* minor cleanups
* added sprite masking effect used by Where's Wally
* fixed column scroll after talking to Charles about how it
works (ddcrew attract mode scrolls properly now)
* went through and fixed VDP priorities in all S18 games; everything should
be correct now, let me know if you find anything not right

Fixed i8051 cpu core bugs [Aaron Giles]
uses correct read/write memory routines for external accesses
support for external IRQs

Fixed an rf5c68 memory access bug [Aaron Giles]

Improvements to Hyper Crash [Angelo Salese]
now mostly working apart from controls and a gfx glitch on the player car

More Taito F2 Blending Improvements [bryan McPhail]
Added the TC0360PRI blending modes to the games with rotation layers. This
includes Pulirula & Liquid Kids. One of the blending modes is new to these
games (not used in Gun Frontier) and I have no way to verify it's actually
correct - someone with a working board will need to verify (Liquid Kids -fish
going in water in attract mode, Pulirula - crystals on level 2).
