Got rid of a memory leak. Rearranged a couple functions.

2000-05-16  Christopher James Lahey  <clahey@helixcode.com>

	* contact-editor/e-contact-editor-categories.c: Got rid of a
	memory leak.  Rearranged a couple functions.

	* gui/minicard/e-minicard-view.c, gui/minicard/e-minicard-view.h:
	Added some code to stop watching the EBook when the canvas is
	destroyed (apparently the canvas is destroyed before our widget is
	destroyed.)
