[Twisted-Python] Change Trac /login link to point to /trac/github/login

If I am not logged in, and click on: https://twistedmatrix.com/trac/newticket It takes me to a page: You are currently not logged in. You may want to do so <https://twistedmatrix.com/trac/login> now. If I click on *do so*, it takes me to: No handler matched request to /login Can this be fixed on the Trac side so that */login* redirects to: https://twistedmatrix.com/trac/github/login ? Or change *do so* to hyperlink to */trac/github/login*? This is a stumbling block when new contributors are asked to open a ticket in Trac. -- Craig
