Stopped using symbolic link for logout

— can’t use symlink on web server, since the user have no permission to
log through ssh. So created a simple index under logout folder that
requires the index form login.
— the index form login was altered so the inclusion of security.php can
be used from inside login folder itself or from other same level
folders, such as “logout”
Addition of index.php for logout folder

File was missing on last commit due to error on github app
Entered constants for db connection with hosting

Can be ignored by other users (database won’t connect remotely anyway)
