Fixed typo in release parameter
Remove duplicate configuration
Remove IdemixLib remnants
Updated script

Various improvements:
 * Proper if clause so condition doesn't break if generate fails
 * Can choose to generate in place, for testing, or securely archive
 * Number of generators set to 6 (needs to be fixed later maybe, as
   silvia_keygen takes an "attributes" parameter)
 * Configure URI to make IdemixLibrary happy
