Implements base.Logic functions in home_settings, site_settings and work
This patch implements the base.Logic funtions needed for making
logic/key_name.py obsolete. This patch defines the needed functions
in home_settings, site_settings and work. All modules in logic/models
now have these functions defined.
logic/models/site_settings.py now inherits from
logic/models/home_settings.py because of their similar connection in
the corresponding models. Please note that the self._keyName for
these two modules still points to logic/key_name.py since entity_type
is still used in views/home.py.
A partial_path and link_name were added to HomeSettings as requested
by SRabbelier.
