What
- remove $wgSecurePollSingleTransferableVoteEnabled from SecurePoll code, and replace it with always on behavior
- remove $wgSecurePollSingleTransferableVoteEnabled from InitializeSettings.php
Why
- easier for new devs working on SecurePoll who don't have to remember to turn this on when wanting to work on tickets related to STV
- seems harmless to have this extra poll type displayed all the time in Special:SecurePoll/create. are there any wiki farms that have this poll type turned off or have a compelling reason to have this turned off?
