port aviz from qt3 to qt4

Aviz 6.1 uses Qt3.  This work is to port AVIZ to Qt 4.8

This is work-in-progress.  The following is the steps being done to do this:
- [X] run with qt4 using qt3 support libraries
- [ ] remove qt3-support classes and deprecated methods

Some reworking of the code is being done (e.g. cleaning the #includes, unused methds, some warnings, some code duplication) but the main focus is to just get AVIZ ported to QT4.   Any bugs from <=6.1 are being noted (as GitHub issues)
