Rendering problems with Lazarus title bars and error box buttons fixed.

Detail:
  Title bars: one of the Ursula redraw optimisations was that if the title
  bar sprites had no mask, then the title bar is no longer filled in before the
  sprites are plotted. Lazarus' toolsprites were falling foul of this, because
  the title bar top and bottom sprites (tbarmidt/tbarmidb) had a lesser height
  than the end sprites (tbarlcap/tbarrcap). Because pre-Ursula Wimps filled
  in the title bar regardless, this may not have shown up in the past. The Wimp
  now has an additional check: if there is a gap between the title bar sprites,
  then it always fills in the title bar background before plotting the sprites.

  Error box buttons: the "illuminated" side of the 3D plinths have always been
  white, so they were getting lost against the white Lazarus UI background.
  Used Ursula Wimp icon colour validation string extension to colour the
  borders a uniform grey.

Admin:
  Tested on a desktop machine, soft-loading the Lazarus Wimp resources.
  Fixes faults 1115 and 1121.
