	* app/core/gimpparamspecs.[ch]: added a shitload of new GTypes and
	corresponding GParamSpecs to use them as PDB arguments.
	Each GimpPDBArgType has one or more corresponding GTypes in the
	core now.

	* app/pdb/gimpargument.[ch] (struct GimpArgument)
	(struct GimpArgumentSpec): removed "value" member because the
	GValue's/GParamSpec's GType carries just as much information now.

	(gimp_argument_type_to_pdb_arg_type): new function which maps
	GTypes to GimpPDBArgType.

	(gimp_pdb_arg_type_to_string): formerly known as
	procedural_db_type_name().

	* app/pdb/gimpprocedure.[ch]
	* app/pdb/procedural_db.[ch]: completely switch to GValue. Use the
	new GParamSpecs for procedure arguments. GimpPDBArgType is only
	used for adding compat args/values of plug-in procedures.

	(procedural_db_run_proc): the va_list expects a sequence of
	(GType, value, GType, value, ..., G_TYPE_NONE) now.

	* app/plug-in/plug-in-params.[ch]: changed accordingly.

	(plug_in_param_defs_check): removed this function.

	* app/plug-in/plug-in-message.c (plug_in_handle_proc_install): use
	plug_in_proc_args_check() instead and initialize the GimpProcedure
	before doing so.

	* tools/pdbgen/app.pl
	* tools/pdbgen/pdb.pl: use the new param spec types and their
	utility functions. Changed argument/value registration
	accordingly.
