First draft of application form + schema

Doesn't get any information other than consortia -- eventually I guess
we'll want to fill in the user's information from some mystical UCL
database that no one will ever give us access to.

It doesn't actually get consortia information *quite* yet, but it has a
stub function which fills in some placeholders, since we didn't have any
of the db stuff in place yet.

That's why it's includes_nodb.php.
