Multiple formatters. Don't write errors to buffer.

Browse Source 
Using python we can check for formatter errors instead of writing the
errors to the buffer. Multiple formatters can be supplied by lists now.

Backward compatibility breaks:
 - Variable names have changed
 - Formatter is specified as one expression
 - gq has been removed, Autoformat should accept ranges
 - python has to be compiled in

To be done:
 - Find easy way to selected default formatter out of available formatter
 - Make autoformat accept ranges
