Fix the index.. this hasn't worked in few years I guess
This is just reaaallly annoying when setting up master
Make these variables greppable.. And in the way fix a bug where the username was never
hinted in the login form
Kill a tiny svn-auth.inc
Use the username from the SESSION, not the (possibly)currently-viewing
Kill md5 and CVS fallbacks..

People that have never logged in since the move to SVN
Are effectively blocked out by this change and they'll have to reset their passwords.
