fixed bug where the root directory path name was being added to the filename twice. It was initially added in the listFiles/listDirectories functions and then added again in the private function list. I modified the code so it is only added in the list function now.

{
	'opengl': ['core/video/opengl/', 'core/gui/base/opengl/'],
	'zip': ['core/vfs/zip/'],
	'script-python': ['swigwrappers/python'],
	'script-lua': ['swigwrappers/lua'],
}
