Implemented dialog for showing movies without covers

Implemented a new dialog to show movies without covers. The view is a
QTreeView with another model. While working on the model several
shortcomings of SmTreeModel were resolved. findValue() now takes another
argument to indicate the column the returned QModelIndex() should
represent. Also, itemAt() was promoted from private to protected. It's
quite useful for derived classes.
