	* app/widgets/gimpwidgets-utils.[ch]: added gimp_text_buffer_save()
	which saves a GtkTextBuffer's contents to a file.

	* app/widgets/gimperrorconsole.c: use
	gimp_editor_add_action_button() and removed all "clicked"
	callbacks, including all file saving code.

	* app/actions/error-console-actions.c
	* app/actions/error-console-commands.[ch]: added the code removed
	above to the action callbacks. Use gimp_text_buffer_save().
