XDebug connect back 

Allows xdebug to connect back to the client making the HTTP request. This is useful for an environment 
where multiple developers are using the same machine and need the server to dynamically connect back to 
their machine for debugging. 

Adds an ini option "xdebug.remote_connectback=[On|Off]" 

You shouldn't enable this in an environment where anyone but the developer can access the machine, 
as it will allow them to view all your source code!
