Added util/e-bit-array.lo.

2001-03-26  Christopher James Lahey  <clahey@ximian.com>

	* gal/Makefile.am (libgal_la_LIBADD): Added util/e-bit-array.lo.

	* gal/util/Makefile.am: Added e-bit-array.c and e-bit-array.h.

	* gal/util/e-bit-array.c, gal/util/e-bit-array.h: New class
	containing the implementation of the bit array used in
	e-selection-model-array.

	* gal/widgets/e-selection-model-array.c,
	e-selection-model-array.h: Refactored the bit array implementation
	into a separate class.

	* gal/widgets/e-selection-model-simple.c: Changed how it clears
	the bit array of the ESelectionModelArray parent class.

	* gal/widgets/e-selection-model.h: Added code to make the
	declaration of EForeachFunc only get included once.
