- Added GetPID to CExecSock
- Significant changes to log module, including:
  - ability to selectively log extra information
  - automatic log rotation
  - logging of server notices
  - probably more things I forgot about since I added them
- Added schnoper module, which caches oper credentials in memory and resends them if your connection drops
- Added znc_identd module, which is basically a much-higher-performance replacement for identfile
  - this module depends on an external program which is not yet committed to source control, which
    acts as an identd and which znc interfaces with via an ExecSock through stdin and stdout
