Better log system #170
Description
We really need a better log system, which will receive logs together with categorisation/filtering information, and then also allow for log sink implementations, which when configured may do obvious things like write filtered logs to file(/s), emit to syslog servers, echo to TCP or Telnet server, etc...
We should also structure any API such that all debug logging code can be compiled out; we don't need the binary clogged with debug log string data and countless calls to format.
