Added database and administrator portal

Created a backend admin area, accessed by entering admin folder within
root site folder.  This admin area requires a username and password,
which are stored in a mysql database.  Added scripts to access the
database I have running on my local machine.  Should be accessible from
the outside as well.  For final version we can simply change the mysql
configuration to point to our final database server, but mine should
work for current testing purposes.  If you need an admin account let me
know an I will make one.
