Add a handler for "model_pre_change" and properly stop editing.

2000-08-02  Christopher James Lahey  <clahey@helixcode.com>

	* e-table-item.c, e-table-item.h: Add a handler for
	"model_pre_change" and properly stop editing.

	* e-table-model.c, e-table-model.h: Added a "model_pre_change"
	signal that gets sent before any row numbers are changed.

	* e-table-sorted-variable.c, e-table-subset-variable.c: Emit
	"model_pre_change" signals as appropriate.

	* e-table-subset.c, e-table-subset.h: Proxy "model_pre_changed"
	signals.
