One of the advantage of having the RMT file at the project root is that we initialize the RMT_ROOT_DIR base on that. Using ```getcwd()``` means that if you do ```./bin/RMT``` it will work, but if you run RMT from the ```bin``` folder it wont work... What about defining the root based on the RMT config location? This could be done here: https://github.com/liip/RMT/blob/master/src/Liip/RMT/Application.php#L75
