PyGObject 3.9.1 Arrives with Several Improvements

PyGObject 3.9.1 uses the correct class for the GtkEditable’s get_selection_bounds() function, test results were added to the g_base_info_get_name function for NULL, the ObjectInfo.get_class_struct() function was added and tests will no longer be built until needed. Moreover, this first development release of PyGObject 3.10 removes Python keyword escapement in Repository.find_by_name, optimizes signal lookup in gi repository, optimizes connection of Python-implemented signals, consolidates signal connection code, and fixes setting of struct property values.
