make sure we call e_table_model_pre_change() before changing the model.

2001-12-03  Damon Chaplin  <damon@ximian.com>

	* gui/e-meeting-model.c:
	* gui/calendar-model.c: make sure we call e_table_model_pre_change()
	before changing the model.

	* gui/calendar-config.c (calendar_config_configure_e_calendar_table):
	removed call to e_table_model_changed(). calendar_model_refresh()
	results in that anyway.
