Changed form submission so that hidden forms are not sent
Fixed a bug with the Checklist that prevented cached downloads from
being served.

When a cached download was found, Checklist.new() was not being called,

these variables being available, and so Checklist#initialize_params() is
now called by itself when a cache is available.
