Adust the as_table tag to render a pick link if appropriate The templates are adjusted to pass on a 'reference' value, which is the url_name of the view from which the entity should be picked. The as_table (and related) function(s) construct and then pass on this argument and enable takes_contex so that we have access to the context of the enclosing template. We only extract ReferenceProperties that end with '_link_id' since that is how all RP's are currently named. It is not possible to create a field with the same name as the RP, as GAE will try to interpret it's contents as the key of an entity before even calling any function we can override.

"""
Pages in Django can are served up with custom HTTP headers containing useful
information about those pages -- namely, the content type and object ID.

This module contains utility functions for retrieving and doing interesting
things with these special "X-Headers" (so called because the HTTP spec demands
that custom headers are prefixed with "X-").

Next time you're at slashdot.org, watch out for X-Fry and X-Bender. :)
