Make nodes with children selectable in picture widget

This was a tough one. Lost in recursion. When selecting nodes with
children in the picture widget, all files having this node as mapping
parent are shown.
Had to make some changes to SmTreeModel::findRecursive for this. I hope
I didn't break anything. If I did, I'll fix it :)
Also disposed of some comments and unused member variables.
