Merge pull request #124 in ZP/z-push from feature/ZP-765-zlog-syslog-refactor to develop

* commit 'a66f8222':
  ZP-765 Fixed missing spaces in log string. Fixed LOGLEVEL_DEVICEID so it works as expected. Fixed access of Log->unauthMessageCache - is now an instance variable. Fixed indentation. Throw a FatalNotImplementedException instead of a simple Exception.
