Tim Allen 5bdf55f08f Update to v101r25 release.

Changelog:

  - SMS: emulated VDP mode 4 graphical output (background, sprites)
  - added $(windres) to icarus as well

I'm sure the VDP emulation is still really, really buggy, but
essentially I handle:

  - mode 4 rendering
  - background scrolling
  - background hscroll lock
  - background vscroll lock
  - background nametable relocation
  - sprite nametable relocation
  - sprite tiledata relocation
  - sprite 192-line y=0xd0 edge case (end sprite rendering)
  - sprite 8-pixel x-coordinate displacement
  - sprite extended size (height only in mode 4)
  - sprite overflow
  - sprite collision
  - left column masking
  - display disable
  - backdrop color
  - 192, 224, 240 height

I do not support:

  - mode 2 rendering
  - sprite zoom
  - disallowing 240 height in NTSC mode
  - PAL mode
  - probably lots more

Changelog:

  - 68K: MOVEQ is 8-bit signed
  - 68K: disassembler was print EOR for OR instructions
  - 68K: address/program-counter indexed mode had the signed-word/long
    bit backward
  - 68K: ADDQ/SUBQ #n,aN always works in long mode; regardless of size
  - 68K→VDP DMA needs to use `mode.bit(0)<<22|dmaSource`; increment by
    one instead of two
  - Z80: added registers and initial two instructions
  - MS: hooked up enough to load and start running games
      - Sonic the Hedgehog can execute exactly one instruction... whoo.
