Made all icons in qresource available for UI

Every registered icon can be chosen as Qt::DecorationRole for all models
at once. Suitable icons must be added to SmGlobals::mIcons. Key is a
descriptive text, value is the icon path.

To make things easier SmTreeModel got two new member functions:
-QIcon decorationIcon() returning the current Icon
-void setDecorationIcon() to set the current Icon
The current Icon is initialized in the constructor from QSettings -
ui/iconfolder

To update the TreeViews connected to the FileSystemModel a little hack
is needed: Just set the QFileIconProvider again. This causes the Model
to update connected views.
