	* app/tools/Makefile.am: build the measure tool again.

	* app/tools/gimpcolorpickertool.c: correct prototypes for some
	functions so we don't get warnings about incompatible assignments
	in "class_init", chain up in "control".

	* app/tools/gimpdrawtool.c: added an implementation of "control"
	which can be called from subclasses so we don't need to call
	GimpDrawTool's methods directly from there.

	* app/tools/gimppaintbrushtool.[ch]: create it's tool options so it
	doesn't crash. Commented out the non_gui stuff. We need a different
	interface for this.

	* app/tools/gimppainttool.[ch]: some cleanups: call the draw tool's
	"control" function, fixed "cursor_update", fixed indentation.

	* app/tools/measure.[ch]: made it work again (properly subclass
	GimpDrawTool).

	* app/tools/tool.c: re-added the non_gui paintbrush STUB()'s

	* app/tools/tools.c: don't allocate the non_gui stuff.
	GimpPaintTool is an abstract superclass, so we cannot create
	an instance of it. Moreover, the current non_gui stuff assumes
	that there is something like a "paint_core" and changes it's
	virtual function pointers, breaking the object system totally.
