* src/gnome-genius.[ch]. src/graphing.[ch]: Remove use of amtk and
	  actually simplify the code in the process.  Also fix an inadvertant
	  API break for plugins (though there are no extant plugins as
	  far as I know).  Add Save toolbar item, fix window delete to act
	  like the quit button

	* configure.ac: remove amtk, raise version
