Made drag events calculate a row and column and signal that information.

2000-08-04  Christopher James Lahey  <clahey@helixcode.com>

	* e-table-group-container.c, e-table-group-leaf.c,
	e-table-group.c, e-table-group.h, e-table-item.c, e-table-item.h:
	Made drag events calculate a row and column and signal that
	information.

	* e-table-selection-model.c, e-table-selection-model.h: Changed
	do_something to take a GdkModifierType.
