Autoscroll update period extended to 12cs to reduce flicker.

Added Wimp_ReadSysInfo 17 to return configured drag-and-drop scroll startup
delay (in cs) because the CMOS storage isn't easy to read.

Identified and bracketed changes from 3.9x responsible for 24-bit icon colours.

defaultfontcolours now works correctly again.

Introduced new icon colour code. This holds icon colours in 24 bits internally
throughout, rather than treating 24-bit colour specifiers as a special case.
This results in the following bugfixes/improvements:
 * 3D faces and moat colours, and slabbed-in action button backgrounds, can
   all be specified in 24-bits
 * fading of icons is now consistent across icon types, and utilises the
   colour range of >16 colour modes
 * 3D borders now get faded along with the rest of the icon
 * action buttons can now contain sprites (background is correct, and sprite
   is not inverted)
 * various cases where anti-alias...

Icon bar now jumps to the back of the stack as soon as a window is opened above
it (excluding menus, dialogue boxes and foregroud windows). This is to avoid
the ambiguous situation when the icon bar can be part-way down the window stack.
Improved co-odination between auto-fronting and Shift-F12 behaviour.
Stopped scroll offset overflow during icon bar scroll.
Numerous features made configurable:
  WimpIconBarSpeed
  WimpIconBarAcceleration
  WimpSpritePrecedence
  WimpIconiseButton
  WimpStickyEdges (although not actually implemented yet)
  WimpAutoFrontIconBar
  WimpAutoFrontDelay
  WimpAutoScrollDelay
To make room for these in CMOS, Wimp<Drag|DoubleClick><Delay|Move> and
Wimp<AutoMenu|MenuDrag>Delay options are now stored in a more compressed form
in CMOS - but the *Configure interface is unaltered.
