Define some global path vars

Defined the site path and config path global vars.   The config path is
one level above the site root for security.  That is were the
config.php is found that contains the DB credentials.
Return some data from the DB.

The getLocationById function connects to the DB, grabs all the data
about a certain location and stores the data in a bunch of vars.  So
far, just returns the name of the place.

TODO: Create a location object that contains all the info and return
that.
