v2.2.0

Added usage statistics - I'd like to know whether i can drop support for old versions of Node. No input args (e.g. filenames) or option values (e.g. preset or encoder settings) are reported at all, only invocation count, flag usage count, module and Node versions.

To opt out of stats, pass the no-usage-stats flag to either .spawn() or .exec(). For example:

hbjs.spawn({ input: "something.avi", output: "something.m4v", 'no-usage-stats': true })
