	* app/core/gimpcontext.h: removed enum GimpContextPropType and
	enum GimpContextPropMask.

	* app/core/core-enums.[ch]: added them here.

	* app/core/gimptoolinfo.[ch]: replaced "gboolean tool_context"
	member by "GimpContextPropMask context_props" so each tool can
	specify exactly which context properties it wants to have
	persistently remembered.

	* app/tools/tools-types.h: changed typedef GimpToolRegisterCallback
	accordingly.

	* app/tools/tool_manager.[ch] (tool_manager_register_tool): ditto.

	Removed the "global_tool_context" and initialize all tool info
	objects from the user_context after creation. Removed the
	PAINT_OPTIONS_MASK #define and use the new context_props stored in
	tool_info insted.

	* app/tools/gimppainttool.h: #define the common properties of the
	paint tools as GIMP_PAINT_TOOL_OPTIONS_MASK (which is OPACITY |
	PAINT_MODE | BRUSH).

	* app/tools/[all tools].c (gimp_*_tool_register): replaced the
	"use_context" boolean by the actual mask of context properties the
	tools need.
