fixed the problem where user 1 and admins could shake hands even with proper settings. now can.
admins now see handshake data above regular user data instead of either/or when admins can shake hands.
now respond to user deletion so we clean up our tables.
user email and picture from standard users table now included as options for handshaking.
see cvs log
Changed some PHP5-only lines to work with PHP4.
There may be issues with this, which is why this doesn't get a full 1.0 version number yet.
