	* gui/widgets/e-minicard-view.c, gui/widgets/e-minicard-view.h,
	gui/widgets/e-minicard.c, gui/widgets/e-minicard.h: Used
	ESelectionModelSimple and the changes to EReflow and EReflowSorted
	to get multiple selection in the minicard view.

	* gui/widgets/test-reflow.c: Changed this to get it to compile
	with the changes to EReflow.
