* src/plugins/relcalc.glade: don't do connect in glade, we need key
	* src/plugins/Leak.py: use os.sep, not + '/'
	* src/plugins/RelCalc.py: Don't keep recalculating relation map of the
	active person, do it once. 50% faster. Make sure all objects can be
	collected by the garbage collector
	* src/Relationship.py: allow to connect to database. Map of first 
	person is stored, only to be removed if database changed, or it
	concerns a different person. This reduces calculation with 50%
	* src/DisplayState.py: don't recalculate home person every time, don't
	call relationship calc on every click, only call it when the people
	are different
