add pro file for qt4 port work
add default color for ColorLabel
update use of QComboBox ctor for qt4
fix: reverting the removal of cstring
fix setLabel methods
slight cleanup of colorboard

fixed #includes.  removed casting from qwidget to
the different dialogs (SpingBoard, AtomBoard) etc.

looks like there was a bug in ColorBoard::bdone() as
pob->closeColorBoard wasnt called.
additional porting of AtomBoard to qt4
fix QComboBox for qt4
fix some deprecated QString
remove uneeded method (typeCopy) from defaultParticles

also cleaned up #includes
fix use of qdialog ctorfor qt4
fix remaining uses of QComboBox::insert/add for qt4
fix AtomBoard to qt4 (finished)

Upgraded to qt4, but there are lots of things
non-qt4 related to be done to this class (e.g. instead
of atomBox being deleted and then recreated each time,
one could just hide and show the different widgets)
