skeleten of a qt version of mussa
One annoying thing about qmake is that each .pro file can only make one
binary. So the old make file which build the fltk gui and more importantly
the boost based unittests is now available as Makefile.noqt.

qmake-qt4 mussagl.pro will generate the qt4 makefile for building the qt4
mussa.

(And I may switch to boost build or scons so I can have one build file
for all the versions).
