Mute optimizer output when verbosity=0

[etianen]

This is currently unimplementable, since collectstatic does not pass the verbosity option to post_process, despite being documented as doing so...

Also came across this issue while extending the post_process command (#24), currently unable to silence the output.

We could parse the commandline parameters for ourselves :)

I've tried this before, but at the time it was impossible to mute the
output of r.js. If r.js now supports muting, then this is definitely a
worthwhile feature. It'll make the tests less noisy too.

Apparently setting the logLevel to 4 should silence every message.

I can confirm changing the logLevel in my build .js file silences the output but looking at the code, django-require already attempts to do this but fails somehow.
