General errors shuould have numbers and unical names and wikipage

Hi
the system of error messages is not perfect in ArduCopter. Every time I get an error message It’s hard to find information about it and messages are different in Mission Planner and in the LOG.

  1. I think that should be separate wiki page with all critical error messages and explanation for them like we have great “Complete Parameter List”.
  2. All error messages should have also the uncial number for example “Compasses inconsistent” should be “Error 017 Compasses inconsistent” for easier identification of the problem.

I can try to help with this but my knowledge about all this error messages is still quite limited.
