The field chooser works now.

2000-06-08  Christopher James Lahey  <clahey@helixcode.com>

	* The field chooser works now.

	* e-table-field-chooser-dialog.c: Make the dialog resizable.

	* e-table-field-chooser-item.c: Requested a reflow on
	realization.  Made the correct column get dragged.

	* e-table-field-chooser.c: Set the height correctly.

	* e-table-field-chooser.glade: Replace the GnomeCanvas with an
	ECanvas.

	* e-table-header-item.c: Receive drags from the new dialog.
