#8 Search should offer to create a site if it can't be found

[Rob Church]

When users are performing a title search, if no results
are found, they should be given the opportunity to
create a new site with that title.

This will require a small addition to search, and a
little bit of tweaking to certain parts of the creation
handlers, to allow the title to come from a GET _or_ a
POST request. This shouldn't be a problem.
