[layerindex-web][PATCH] views: add ability to force https URL in layer review emails

[Paul Eggleton <paul.eggleton@linux.intel.com>]

At the moment the URL that is presented in the review email will have
http:// or https:// prefix depending on what the user who submitted the
layer was using, but that's irrelevant - we actually want https:// if
the server is capable of it since the reviewer may be redirected to log
in (and Django's login_required decorator will always redirect to the
login page if http is being used as far as I observed, which is a bit
annoying if you are already logged in.) Add a setting which if enabled
will substitute https:// as the prefix.
