v1.4.1

Breaking changes: stderr will no longer default report. See below!

Added options.reportStderr to the Thread Manager, which will now default to false. This prevents parroting (duplicate messages) of uncaught exceptions, console.error|warn, and other error messages. You will want to activate report errors if you're using a non-traditional process, such as something other than Node (like an AV Encoder).

Added support for custom command arguments; this helps add "--trace-warnings" and other command line arguments. Either pass a string to have it automatically split on "space" or take granular control (say for file names) by passing an array of strings that will not be modified.
