	* app/tools/Makefile.am
	* app/tools/gimpimagemaptool-settings.[ch]: new files containing
	all the recent settings and settings load/save GUI and code.  Got
	rid of shortcut loading/saving using shift+click. Added default
	implementations of ::settings_load() and ::settings_save().
	The GUI is currently horrible, work in progress!

	* app/tools/gimpimagemaptool.c: removed the settings code here.

	* app/tools/gimpcurvestool.c * app/tools/gimplevelstool.c: don't
	pack the load and save buttons, this is done generically for all
	tools now.

	* app/tools/gimpbrightnesscontrasttool.c
	* app/tools/gimpcolorbalancetool.c
	* app/tools/gimpcolorizetool.c
	* app/tools/gimphuesaturationtool.c
	* app/tools/gimpposterizetool.c
	* app/tools/gimpthresholdtool.c: set the load/save related members
	of GimpImageMapToolClass.
