few documentation tweaks
[Anonymity] Added back NeffKeyShuffle
[Anonymity] Fixed CSDCNet Blame
- made it work with the new dissent code
- fixed lots of off by 1 errors
- fixed overlay forwarding so servers can contact any client
- added in some broken tests to check for a malicious client
Cleaning up CSDCNet
- BadMembers now contains Ids
- Cleaned up the bad round testing
- Added more blame analysis
- Found a critical missing path in the blame analysis that actually
  impacts our earlier results (albeit insignificantly thanks to the super
  slow shuffle and even the slowish verdict)
