	* app/Makefile.am: took gimpcontextpreview.[ch] out of the build
	but still left the sources there as reference.

	* app/app_procs.c: initialize the render stuff before creating the
	toolbox (needed for the previews).

	* app/devices.c
	* app/indicator_area.c: use GimpPreviews instead of
	GimpContextPreviews.

	* app/context_manager.[ch]: create the global data lists here
	because they now must exist before any context is created.

	* app/brushes.[ch]
	* app/gradients.[ch]
	* app/palettes.[ch]
	* app/patterns.[ch]: removed them here.

	* app/gimpcontainer.[ch]: added a "freeze_count" and emit the
	"freeze" and "thaw" signals accordingly.

	* app/gimpcontext.[ch]: greatly simplified the way how the
	contexts connect to the data lists (simply keep them connected all
	the time). Also removed all those ugly explicit update functions
	because "thaw" callbacks do this job now.

	* app/gimpdata.c: a GimpData object now becomes dirty on
	"name_changed"; "dirty" now triggers "invalidate_preview" because
	the context does not dispatch these signals any more soon.

	* app/brush_select.c
	* app/convert.c
	* app/gimpdnd.c
	* app/gradient_editor.c
	* app/gradient_select.c
	* app/pattern_select.c
