	* tools/pdbgen/pdb/gradient_edit.pdb: applied a patch from Shlomi
	Fish that adds lots of gradient edit functions to
	gimpgradient.[ch] and makes them available through the PDB.
	Fixes bug #129675 and bug #129678.

	Did some cleanups / enhancments to the patch:

	* app/core/gimpgradient.[ch]: changed the naming scheme of the new
	functions and changed old functions to match the new scheme.
	Introduce a "freeze_count" and public freeze()/thaw() API which
	enables subsequent gradient changes without "dirty" being emitted
	all the time.  Added GimpGradient parameters to all functions
	which modify the gradient.

	* app/widgets/gimpgradienteditor.c: use the new freeze/thaw
	stuff to keep the gradient from updating when not in
	"Instant Update" mode.

	* app/actions/gradient-editor-commands.c: removed all gradient
	editing code and call the new core functions.

	* libgimp/Makefile.am
	* tools/pdbgen/pdb/gradient_edit.pdb: changed the namespace of all
	added functions. Generate libgimp wrappers for them..
