Allow for user object to be empty. Fixes #317.

If a flavour has only one skin, the skin selector will be omitted.  This
omits the user[setting_skin] field, and because that's the only
user[...] field on the page, the entire user object will not be present
in the request handler's params object.

This commit accounts for that scenario by avoiding params.require(:user)
and instead picking out what we need from the params hash.
