	Bug 552413 – Script triggers Gimp-Core-CRITICAL

	* tools/pdbgen/pdb/image.pdb
	* tools/pdbgen/pdb/layer.pdb: add some more checks that produce
	proper PDB error messages when adding and removing layer masks
	instead of having the code run into assertions in the called core
	functions. Also add some more checks when removing layers,
	channels or vectors.

	* app/pdb/image-cmds.c
	* app/pdb/layer-cmds.c: regenerated.
