System windows (eg STB command window) can now have window furniture but no 1-pixel borders.

Detail:
  The code that checked for a Wimp_Initialise version number of >= 380 before
  applying the new interpretation of title foreground colour &FF was broken:
  it was checking the current task handle instead of the task handle of the
  window's creator. A few other things needed tampering with in order to ensure
  that the window's task handle word is correctly set up at the time that the
  colour check is performed.
Admin:
  Tested in a desktop build, using STB resources.

Version 4.43. Tagged as 'Wimp-4_43'
