Make use of PolyModel for Works, Documents, etc. Add some (but not all) of the missing Models related to Documents. Refactor site settings to be useful for any "/home" page view. Make the resulting home settings store a reference to the Document, rather than looking up the Document by a hard-code key name. This is to set the stage for Document editing being generic, and then being able to select from some existing documents which one to use as the "/home" static content. This makes it possible to pre-edit several Documents, have them Reviewed, and then quickly change the "/home" page content as a setting, rather than editing the Document in the settings form (though settings forms might still embed the current document into their form for convenience).

Fixed not working "Create New User" view which was caused by adding key_name into User Edit Developer view. This commit divides edit() view function in soc.views.site.user.profile into edit() and create() request handlers. New create() request handler is used only in "Create New User" view and has specific form validation functions and uses updateOrCreateUserFromId() instead of updateUserForKeyName().

Add ModelWithFieldAttributes *before* PolyModel, so that everything does not become a "ModelWithFieldAttributes" in the Datastore. The way PolyModel works, each Model class hierarchy is stored in the Datastore as the class that directly inherited from PolyModel. So, we do not want to insert ModelWithFieldAttributes *after* PolyModel by inheriting *from* PolyModel, or everything would just be a ModelWithFieldAttributes in the Datastore, instead of Person, Work, Group, etc.

Add the third-party PolyModel class. This class supports inheritance in Google App Engine Datastore Model classes.

A key_name controller module to collect all of the name...() functions that compose Model entity key names, plus some minor changes to other controller modules to illustrate the proposed use.

Fixed missing urlparse import in request_helpers which cause /user/profile and /site/user/profile not to work at all. Removed not used module imports in response_helpers.py.

Replace mock-up of sidebar with first draft of dynamic sidebar functionality.

Minor tweaks to Site menu item names to make them more descriptive.

Major refactoring, to switch from using inheritance from soc.logic.menu classes to an envelope-letter model instead.

Sidebar-building controller, with a TODO remaining to implement marking the current page as "selected".
