Actors and genre edit

Implemented widgets for actor and genre editing of movies. Created new
MappingTableWidget for both genres and actors and revamped
ArchiveTreeView to show 2 widgets below the FilesTreeView separated by a
splitter.

While testing the new setup several bugs were fixed:
-an SQL syntax error in FilesTreeModel
-fixed SmModelSingleton to properly work with table names

I also changed the signature of MappingTableModel::addMapping for the
ease of use and added MappingTableModel::removeMapping.
MappingTableModel got 2 new convenience functions:
1. bool contains(QString) to check if an item is already present
2. QModelIndex find() to get the index of a specific value from the
model.
