	Complements the fix for bug #344818:

	* libgimpbase/gimpbaseenums.[ch]: added new enum 
GimpPDBErrorHandler.

	* tools/pdbgen/enums.pl: regenerated.

	* app/plug-in/gimpplugin.[ch]: added error_handler to 
GimpPlugIn.

	* app/plug-in/gimpplugin-message.c 
(gimp_plug_in_handle_proc_run):
	only display an error message for a failed procedure call if the
	plug-in's error-handler is set to 
GIMP_PDB_ERROR_HANDLER_INTERNAL.
	
	* tools/pdbgen/pdb/plug_in.pdb: added PDB getter and setter for
	the plug-in's error-handler.

	* app/pdb/plug-in-cmds.c
	* app/pdb/internal-procs.c
	* libgimp/gimpenums.c.tail
	* libgimp/gimpplugin_pdb.[ch]: regenerated.

	* plug-ins/common/file-compressor.c
	* plug-ins/file-uri/uri.c: set the error-handler to
	GIMP_PDB_ERROR_HANDLER_PLUGIN as these plug-ins are forwarding 
the
	error with their return values.
