[forms] remove dead code and simplify inlineviews creation
remove AutomaticEntityForm.should_inline_relation_form which is not
used anywhere and comes from a time where uicfg did not exist.
remove test for "force_<rtype>_display" presence in req.form to
determine whether or not the inline creation form should be displayed.
Schema of the data
------------------
First take a look at the data schema_ then try to remember that you are browsing
through a heap of data by applying stylesheets to the results of queries. This
site is not a content management system with items placed in folders. It is an
interface to a database which applies a view to retreived data.
