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.

The below HTML code was generated and appended by Google. It's purpose is
to display a logging console in the browser. It's appearing here because
either:
(a) the CGI parameter "debug" was in the URL
(b) the cookie "_ah_severity" was present in the HTTP request
To stop this from being appended, you should remove the CGI parameter
"debug" from the request URL and then either click the "Close" link on the
logging console, or delete the "_ah_severity" cookie.
All element ids used by the code for this logging console are prefixed
with "_ah", all cookies used are prefixed with "_ah", and all classes and
functions are in the namespace "AH".
