* src/RelImage.py: replace system call with Utils.search_for

* src/Utils.py: added search_for to look for an executable in the current
path

* FAQ: removed question 18 (how fast is GRAMPS)
* src/PeopleStore.py: set sort data for top level nodes. Allows the first
and last nodes to be sorted properly.
