Patch from James Fournie -- fixing org tree fleshing depth.

====
I was having a horrible time getting the hasCommonAncestor() function
to work in the circ Javascripts.  I eventually discovered that
ScriptBuilder.pm was making a cstore actor.org_unit search with flesh
= 2, which limited the search to org units above depth 2.  My org
units were depth 3.  I changed the cstore flesh to -1 and this seems
to retreive all org units.  I also found an similar problem in
AppUtils.pm
