	Step one towards enabling tool cancellation by other means than
	mouse button 3 and towards proper "clicked" semantics.

	* app/tools/tools-enums.[ch]: added enum GimpButtonReleaseType
	which can be one of { NORMAL, CANCEL, CLICK } (click is curently
	unused).

	* app/tools/gimptool.[ch] (GimpTool::button_release): added
	"release_type" parameter.

	(gimp_tool_button_release): if the state contains
	GDK_BUTTON3_MASK, call the tool's button_release() with CANCEL,
	use NORMAL otherwise.
