Qt port is almost complete (at least it compiles)

Major change:
* struct DataEntry has become class Session with sub-classes XSession and VSession
* functions from addInfo.cpp, addPrinters.cpp, addScanners.cpp, readLinSess.cpp, readXmlDir.cpp, runImage.cpp have been moved to XSession and VSession

Several minor changes:
* new files globals.h and globals.cpp for global variables (replaces constants.h and paths.h)
* replaced (all) libxml2, (much) std:: and (most) boost:: stuff by Qt stuff

Things left to do:
* remove tons of debug printfs
* show error messages on errors
* tidy up anyoption stuff in main()
* highlight session run previously
* readGroupXml stuff
* tree view (with "X Sessions" and "Virtual Sessions" sections) instead of list view for session selection
