	Bit of a large checkin this - it's basically three things:
	  1 - GimpModules using gmodules to dynamically load and
	       initialise modules at gimp start of day.
	  2 - Color selectors now register themselves with a color
	       notebook.
	  3 - progress bars have been cleaned up a bit, so now have
	       progress indictations on all transform tool and gradient
	       fill operations.  Not done bucket fill, but that seems to
	       be the next candidate.

	New directories:
	* modules/: new directory for dynamically loadable modules.

	New files:
	* modules/.cvsignore
	* modules/Makefile.am
	* modules/colorsel_gtk.c: GTK color selector wrapped up as a
	    color selector the gimp can use.

	* app/gimpprogress.[ch]: progress bars within gimp core, either as
	    popups, or in the status bar.  This is mainly code moved out
	    of plug-in.c

	* app/color_notebook.[ch]: color selector notebook, implementing
	    very similar interface to color_select.h so it can be used as
	    a drop-in replacement for it.

	* libgimp/color_selector.h: API color selectors need to implement
	    to become a page in the color_notebook.

	* libgimp/gimpmodule.h: API gimp modules need to implement to be
	    initialised by gimp at start of day.

	Modified files:
	* Makefile.am: add modules/ to SUBDIRS
	* libgimp/Makefile.am: install gimpmodule.h and color_selector.h
	* app/gimprc.[ch]: recognise module-path variable.
	* gimprc.in: set module-path variable to something sensible
	    (currently "${gimp_dir}/modules:${gimp_plugin_dir}/modules").
	* app/Makefile.am: build color notebook and gimpprogress
	* app/app_procs.c: register internal GIMP color selector with
	    color notebook.
	* app/asupsample.c: call progress function less frequently for
	    better performance.
	* app/asupsample.h: progress_func_t typedef moved to gimpprogress.h
	* app/blend.c: make callbacks to a progress function
	* app/color_area.c: use a color notebook rather than a color selector
	* app/color_panel.c: ditto
	* app/color_select.c: export color selector interface for notebook
	* app/color_select.h: color_select_init() prototype
	* app/flip_tool.c: flip the image every time, rather than every
	    second click.
	* app/interface.c: move progress bar stuff out to
	    gimpprogress.c.  Make the code actually work while we're at it.
	* app/interface.h: move prototypes for progress functions out to
	    gimpprogress.h
	* app/plug_in.c: load and initialise modules (if possible). Move
	    progress bar handling code out to gimpprogress.c
	* app/plug_in.h: keep only a gimp_progress * for each plugin, not
	    a whole bunch of GtkWidgets.
	* app/scale_tool.c
	* app/rotate_tool.c
	* app/shear_tool.c
	* app/perspective_tool.c: progress bar during operation.
	    De-sensitise the dialog to discourage the user from running
	    two transforms in parallel.
	* app/transform_core.c: recalculate grid coords when bounding box
	    changes.  Only initialise the action area of the dialog once,
	    to avoid multiple "ok" / "reset" buttons appearing.  Undraw
	    transform tool with correct matrix to get rid of handle
	    remains on screen.  Call a progress function as we apply the
	    transform matrix.  A few new i18n markups.  Invalidate
	    floating selection marching ants after applying matrix.
	* app/transform_core.h: transform_core_do() takes an optional
	    progress callback argument (and data).
	* plug-ins/oilify/oilify.c: send progress bar updates after every
	    pixel region, not only if they processed a multiple of 5
	    pixels (which was quite unlikely, and therefore gave a jerky
	    progress indication).
