Login works, Next step is finishing logout and PHP magic
Need to change the other existing PHP to use the new DB and Tools classses
Added Login/Logout functionality

Hard coded the logout() functionality in the logout.php since
it wouldn't work right. Login switches to Logout when logged in.

Is active or inactive depending on current page. Next step, add logout
to the change status page.
Added logout to ChangedStatus.php; minor fixes

Fixed some closing tags, added the ability to logout from
multiple changes
