[web2py] How about auth.define_tables(..., format='...')?

[Ray (a.k.a. Iceberg)]

Hi Massimo,

How about add a new parameter to auth.define_tables()? As below.

  def define_tables(..., format=''%(first_name)s %(last_name)s (%
(id)s)"):
     ...
    db.define_table(..., format=format)
    ...

The idea is to let user has a change to customize it. Currently we can
override this value at all.

Regards,
Ray
