More child testing.
Updated the git files to ignore all non-needed Qt files.
Removed the .edl files in mainw... because they are changed every time
the user re-guffs.
Added a top level Qt examples folder, and right now the mainw application
is running using it.
Merge branch 'master' into openGL2
Added and got the testOpenGL application working under Qt.
Added more applications to the Qt build library, including:
mainFltk1
mainfd1 and 2
mainEfis
Merge branch 'master' into openGL2
