* 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

This can be a time intensive calculation, so we only want to do
it if persons are different than before.
Eg: select a person, then double click, will result in calling
three times to construct build the statusbar. We only want
to obtain relationship once!
This means the relationship part of statusbar only changes on
change of row.
