	* app/plug-in/plug-in-proc.[ch] (plug_in_proc_def_get_sensitive):
	new function which checks a GimpImageType against the
	proc_def->image_types_val mask.

	* app/actions/plug-in-actions.c: use the new function here. Also
	separated setting the "Repeat last" and "Reshow last" actions'
	labels from setting their sensitivity and made them use the same
	sensitivity logic as all other plug-in actions. Fixes bug #149567.
