added Store/Recall buttons for one-click saving and loading of curves. 

2004-06-22  Bill Skaggs  <weskaggs@primate.ucdavis.edu>

	* app/tools/gimpcurvestool.c: added Store/Recall buttons for
	one-click saving and loading of curves.  Should create stock
	labels for them.  Hopefully resolves bug #75558.
