Make findNearestUsers() code in soc/logic/site/id_user.py more generic and move it to soc/logic/model.py. Orginal findNearest...() functions in id_user.py are now convenience wrappers. Add typed-query string construction functions to model.py. Move getFulLClassName() from key_name.py model.py, since it has more to do with Model types than key names. Swap 'offset' and 'limit' and make 'limit' arguments non-optional. Also, stop adding 1 inside the ...ForLimitAndOffset() functions and make the callers do it (since it was being added for a very UI-specific reason of whether or not to display a "Next>" link).
