Remove package that's only a twisted requirement; will be pulled in by twisted
Bump the version of txsockjs so it installs
Make the crypt function flexible in what it accepts
Make pycrypto an optional requirement
Make a note in the example config of modules that require pycrypto
Removing these last time was not correct until twisted provides a way to not need them
