Numbering compiler error messages?

I still think it's a good idea for D. It was proposed time ago.

It has two advantages:
- Make it easier to find info about an error. The info can 
explain the bug, show clear examples of the mistake, and how to 
fix it.
- Give some discipline, order and systematicness to the world of 
D errors/warnings.
