grc: Add dir_select parameter type
This commit adds a new parameter type to GNURadio Companion that allows
you to select directories using a gui. This functionality is
very similar to that of the previously available "file_open" and
"file_save" parameter types, and mainly differs by calling GTKs file
chooser with FileChooserAction.SELECT_FOLDER.
