Minor refactoring.
Got rid of 'define' preprocessor directive to prevent debugging hell.
Abbreviations should be widely known and unambiguous.
New movement functionality. SCgMovingHelper class was introduced to
provide different moving strategies.  Previous solution with calling
sync() method from paint() was temporary reverted as it didn't work as
expected.
Added new SCgGraphicsWidget classes: SCgProgressBar, SCgMessageBox, SCgGroupBox, SCgLabel, SCgLineEdit
to merge repos.
Merge remote-tracking branch 'upstream/master'
Sun menu for visual objects. Initial implementation.
Merge pull request #50 from zooner/sun_menu
