Add a generic method for getting a Keyname
This patch will make logic/key_name.py obsolete in the future when
everything is compliant with base.logic.
This also makes the naming of already compliant logic modules generic
and also fixes the _name field to be consistent with the naming in
key_name.py.
Note: This does not use Group/Sponsor, Group/School,
Group/Organisation or Group/Club.
