	Fixed & cleaned up paint function registration to work without
	GUI. Finishes core/GUI separation for the paint tools:

	* app/core/gimppaintinfo.[ch]: removed "gchar *pdb_string" all over
	the place since we don't stroke using the PDB any more.
	(gimp_paint_info_new): create paint_info->paint_options here so
	the paint system is fully initialized when there is no GUI.

	* app/paint/paint.c: removed pdb_string stuff here, too.

	* app/core/gimptoolinfo.[ch]: create tool_info->tool_options
	only if tool_info->tool_options_type is not the same type
	as paint_info->paint_options_type (if we are no paint tool).

	* app/core/gimptooloptions.c: removed G_PARAM_CONSTRUCT_ONLY from
	the "tool-info" property. Instead, changed
	gimp_tool_options_set_property to ensure that it is only set once.

	* app/core/gimp.c (gimp_initialize): moved paint_init() after
	data_factory creation (was in gimp_init()), since GimpPaintInfo
	now creates the GimpPaintOptions, which are GimpContexts, which
	need gimp->*_factory to be constructed.

	* app/tools/tool_manager.c: don't create tool_info->tool_options
	here (it's not the job of the tool_manager to set up the core
	paint system correctly, it must be already initialized before any
	tool_manager function is called).

	Made "Stroke Selection" and "Stroke Path" work the same way:

	* app/paint/gimppaintcore-stroke.[ch]: added new function
	gimp_paint_core_stroke_boundary() which strokes without using
	the PDB.

	* app/core/gimpimage-mask.c (gimp_image_mask_stroke): use it
	instead of using the PDB. Enables all available paint options for
	stroke operations. Fixes bug #119411.

	* app/gui/vectors-commands.c (vectors_stroke_vectors)
	* app/core/gimpimage-mask.c (gimp_image_mask_stroke): removed all
	code which tries to figure how to stroke and simply look at the
	active tool's tool_info->paint_info, since it is always set up
	correctly now.
