Major site restructuring, also deleting of many unused or obsolete documents The new structure is as follows: <entity>/list - list all <entitie>s <entity>/create - create a new <entity> <entity>/show/<key fields> - public page for <entity> <entity>/edit/<key fields> - edit a <entity> <entity>/delete/key fields> - delete a specific entity

Fix sponsor key field extraction When extracting key field there is no sponsor or user object, instead only their link names are known.

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.
