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.

"""Model of a Response to a Quiz.
A Response is the "collection point" for a set of specific Answers to the
Questions that make up a Quiz.
In addition to the explicit ReferenceProperties in the Response Model, a
Response entity participates in these relationships:
answers) a 1:many relationship between Answer entities and this
Response. Each Answer points to the Response to which it is a part.
The collection of Answers that make up a Response is implemented as
the 'answers' back-reference Query of the Answer model 'response'
reference.
proposal) an optional 1:1 relationship where a Proposal placed its
Answers to a Quiz associated with the Proposal. This relation is
implemented as the 'proposal' back-reference Query of the Proposal
Model 'response' reference.
