Added minicard and text stuff.

	* widgets/Makefile.am: Added minicard and text stuff.

	* widgets/e-minicard.c, widgets/e-minicard.h,
	widgets/e-minicard-label.c, widgets/e-minicard-label.h: Added
	canvas items for the minicard view in the contact manager.

	* widgets/test-minicard.c, widgets/test-minicard-label.c: Tests
	for the minicard items.

	* widgets/e-text.h, widgets/e-text.c: New canvas item.  Based on
	GnomeCanvasText.  Adds ellipsis capabilities.  Used in
	e-minicard*.[ch].

	* widgets/.cvsignore: Added minicard-test and minicard-label-test.
