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).

Takes two datetime objects and returns the time between d and now
as a nicely formatted string, e.g. "10 minutes". If d occurs after now,
then "0 minutes" is returned.
Units used are years, months, weeks, days, hours, and minutes.
Seconds and microseconds are ignored. Up to two adjacent units will be
displayed. For example, "2 weeks, 3 days" and "1 year, 3 months" are
possible outputs, but "2 weeks, 3 hours" and "1 year, 5 days" are not.
