knotty: add quiet output mode

Quiet output mode disables printing most messages (below warnings) to
the console; however these messages still go to the console log file.
This is primarily for cases where bitbake is being launched
interactively from some other process, but where full console output is
not needed.

Because of the need to keep logging all normal events to the console
log, this functionality was implemented within the knotty UI rather
than in bb.msg (where verbose mode is implemented). We don't currently
have a means of registering command line options from the UI end, thus
the option actually has to be registered in main.py regardless of the
UI, however I didn't feel like it was worth setting up such a mechanism
just for this option.
