Closes #422  Redirect for Subscription Approval/Denying redirects to either, "1" or, "0", and not the actual URL
Closes #423 Enabling Subscription Approval/Denying also enabled Closed-Loop Opt-in
This adds more fixes to subscription request, without needed to send a confirmation email, and I added another test to try to confirm the fixes. 

This also fixes an issue that " Limit Subscription Confirmation Sending " doesn't work for Subcription Requests. 

Hmm, maybe, "Subscription Confirmations" should be renamed, "Subscription Requests" to avoid a mass amount of confusion.
This disables the, "_check4htacces"... check, as it's ridiculous: not only does it check for an .htaccess file, which is good! But it checks for the exact .htaccess file it wants, which is bad bad bad, since this .htaccess file is very much wrong. Sigh.
