xdebug for symfony testing

Update: The latest version of mamp already comes with xdebug so all we need to do is just to uncomment that xdebug line in php.ini.

Download revised version of xdebug from Komodo

Replace the xdebug.so from MAMP php lib folder (e.g. /Applications/MAMP/bin/php5/lib/)

uncomment the xdebug line from the php.ini file.

Restart apache and the test should run~
