Added php code
Updates, changed up some PHP.
Reorganized directories. Fixed a lot of PHP bugs. (Still learning it.)
Finished PHP, aside from extra qualifications. Things work though, and that's great.
Changed LDAP functionality to connect with the current Webauth'd user, rather than use my own credentials. Also I added a normal-mapping step to the rendering process so that all edges are highlighted, not just those between rooms and between the model and background.
Un-deleted 'constants.php'
