Clean up the DirectoryIndex mess.

* Remove DirectoryIndex from the .htaccess file. This file set the index for every directory to start.php3, which was wrong. * Change index.html to redirect to index.php3. * Change start.php3 to redirect to index.php3. I left the start.php3 script in place (one line script) so that existing bookmarks work. * Move the code that used to be in start.php3 to the top of index.php3; this is the code that would zap to the My Emulab page when the user was logged in (and in https mode). Much simpler now.

-# The point of this mess is to redirect people from the top level 
-# index page (ie: no page specified) to the most appropriate page.
-#
-# 1. If no UID cookie comes in from the browser, just redirect to the
-#    to the index page, maintaining secure/insecure mode. That is, if the
-#    page was accessed via https, use https when redirecting to the index
-#    page.
-#
-# 2. If a UID cookie comes in, check to see if the user is logged in. If
-#    so, redirect to his user information page. If the user is logged in,
-#    but came in with http, then we cannot actually confirm it (MAYBEVALID),
-#    since the hash cookie will not be sent along, so we redirect back using
-#    https so that we can confirm it (hash cookie sent). If it turns out that
-#    the user is not logged in, fall back to #1 above.
