New Class: SmTreeView

Code reusage: all 3 tabs had the same funtions: readHeaderConfig,
writeHeaderConfig and toggleHeader, so turn it into a class derived from
QTreeView.

Unfortunately mATree didn't do things as later added Views, so it took
some time to find the culprit in SheMov::readSettings :( Hopefully I
didn't break too much...
