Add Qt4 windowport

Originally by Ray Chason for 3.4.3, based on the Qt windowport by
Warwick Allison. The look and feel is mostly the same.

Some improvements over the Qt 3 interface are:

* Panes are resizable
* Full support for IBMgraphics, and walls and corridors are drawn with
  graphical primitives for a continuous appearance no matter what the font
  says
* Lots of irritating glitches fixed
* Menus support proportional fonts correctly

Adding this because the old Qt windowport cannot be compiled on Qt4,
even with Qt3 compatibility stuff.

TODO:
 - background map glyphs
 - status hilites
 - menucolors
