Merged in RISC OS 4.02 changes (including ROM patches). Also som bugfixes.

Detail:
  RISC OS 4 changes:
  * Font blending for desktop font (based on NC code, but now configurable)
  * 3-D window/menu/iconbar borders
  * Textured menu backgrounds
  * Loss of rubout box in unfilled text+sprite icons
  * *WimpVisualFlags controls various aspects of cosmetic changes above
  * Iconise button "slot" glyph slightly shorter (but only adopted in the RO400
    Resource directory)
  * Command window has front-window flag set
  * Byte at +39 of the window block has gained two new flag bits:
      bit 2 set => this window must never be given a 3D border
      bit 3 set => this window must always be given a 3D border
      (note that ResEd erroneously created windows with both bits set,
      this case is treated as though both bits were clear)
  * Another two colour specifiers on the end of C validation string command
    for icons controls the foreground and background colours to be used when
    the icon is selected
  * Pointer shape is correctly reprogrammed by the creation of icon
    underneath it
  * Full stops in writable icons are treated the same as spaces from the
    point of view of cursor navigation
  * spritesize routine returns a size of 0 if the sprite didn't exist
    (probably fixes some rendering problems)
  * Adjust-click on back icon brings window to front
  My changes:
  * DeleteRight turned on
  * Icon bar title background is set to default in all resource sets (avoids
    translation table recalc)
  * Error box title now cream across all resource sets
  * RISC OS 4 changes made 32-bit compatible / high addresses safe
  * Undocumented FullIconClipping option disabled
  * Command help made consistent for internationalised and non-
    internationalised builds
  * WimpVisualFlags defaults made sensible
  * Menu side width affected by ThreeD option at *run* time not assemble time
  * Right-clicking on menus with writable items no longer data aborts
  * Auto-opened menus are now at RHS of current icon (matches RISC OS 3.1)
  * Colour menus were knackered unless menu tiling was enabled
  * Fixed a bug whereby adding messages to a task that wanted all messages
    actually caused it to lose all other messages. The RISC OS 4 fix for
    this didn't work
  * Fixed bug introduced in version 4.76: tasks that wanted no messages got
    all of them
  * Autoscrolling is updated every 8 cs rather than every 12 cs
  * Added menu texture to pre-RISC OS 4 sprites files
