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.

"""
FIFE Backwards Combatibility Layer
==================================

This module can be imported if you want to
run code that wasn't adapted to API changes in FIFE.

2008.1
------

 - Animation.addFrame now expects a fife.ResourcePtr instead of an fife.Image
 - Pool.getIndex is just an alias for Pool.addResourceFromFile.
 - EventManager.setNonConsumableKeys is superseeded by EventManager.setKeyFilter
