    mapping: Don't parse the first two fields as bindings
    
    Thanks to changes introduced by the previous commit, the mapping object
    can always expect to be fed a complete mapping string, with he first
    field being the GUID and the second one being the gamepad's name.
    
    These two first fields must hence be skipped.
