	* thunar/thunar-list-model.c: Instead of resolving the ids for the
	  "destroy" and "changed" signals on ThunarFile everytime we need to
	  register it, we query the signal id in the constructor and remember
	  it. In addition, instead of creating a closure for every signal
	  registration on a ThunarFile, we create a closure for "changed" and
	  a closure for "destroy" in the constructor and reuse that closure
	  everytime we need to register a signal handler.
	* thunar/thunar-list-model.c: Watch hidden files for "destroy" condition
	  as well.
	* thunar/thunar-trash-file.c: Emit the "changed" signal whenever the
	  "empty" property on the trash manager changes.
	* thunar/thunar-file.{c,h}: Add a method thunar_file_changed(), which
	  is used by derived classes to emit the "changed" signal on a given
	  ThunarFile.
