Johannes Schickel 7c5cf1b400 GUI: Add helper to SaveLoadChooser, which uses the currently active target. 
This reduces the code duplication in all client code, which formerly duplicated
the querying of the plugin, game id etc. and now simply calls the newly added
method runModalWithCurrentTarget() on a SaveLoadChooser object.
