Fix get/set bug in datamodel
Remove dependency on nofw DI functions

Shifted read security to helper function.
Override find() to return Models instead of Items.
Fixup tests, ANSI quotes is now default
Fixup connector test, check strings after lower
Allow override of just creating new Dataitem.

Overridding the entire set function just to add params to the
dataitem ctor was too much work/error prone.
