Fix for Git Issue #2.
Migrated to Express 4.
This caused an issue with the way cookies look and are accessed
from the session, so I decided to get that information from the
api calls instead.  So on return /api/login and /api/isloggedin
return userid, email and tournament in addition to a status
message.  There is no need to access cookies on the client side
now.
Lastly, found a minor omission in the style.css file which made
the login form fields extend beyond their container.  Fixed as well.
