  [Not fully implemented - for now leaves at least 16MB free if only
  one RAM area; was 1MB].
* Added HAL_USBControllerInfo, HAL_MonitorLeadID and HAL_Video_Render.
* Added HAL->OS call OS_IICOpV.
* OS_MMUControl now allows independent control of I and C bits.
* Added facility to deactivate keyboard debounce (magic word "NoKd" in
  R2 in KeyV 0).
* Fixed problem with RAM amounts not a multiple of 4MB.
* Supremacy bit (in VDU 19) now sets all 8 bits of supremacy.
* Added PaletteV 14 (reads gamma tables).
* Added Supremacy transfer functions (like gamma correction, but for
  supremacy). Allows easy global supremacy effects in a mode-independent
  fashion. Controlled with PaletteV 15,16.
* Added modes 50-53 (320x240, 1,2,4,8bpp). Intended for small LCD.
* Added 13.5kHz versions of TV modes (selected by Hdr:Machine).
* Upped desktop version to 5.06.
