Include the new stylesheet

Some files will have to be updated to return this page to its former
glory.
Changed some design

Made update to css file
Made update to basic.php
Made update to index.php
Removed some lines
Implemented saved sessions

login.php now sets cookies to automatically log in the user if they
ask for it.
Made logout remove the cookies

Leaving the cookies in the browser after a logout will instantly cause
the user to get logged in again upon the next page visit (to a page with a
login check).
Move most of the core functionality over to PDO

Since the mysql_* functions are being removed in PHP 5.6 and being
future-proof is generally a good idea this seemed like a good idea.

Any new functions added to the shared library should use PDO instead
of the old mysql functions and new features added to the projects
should preferably use the new pdoConnect() method to connect to the
database instead of dbConnect().
