Provide a -q options to suppress unnecessary console output

[bennoleslie]

It would be nice if the jsx tool provided a mechanism to suppress the output of built Module("...")

A common pattern used in other command line tools would be to provide a -q option (although an alternative would be to suppress the output by default and provide a -v option to make verbose output).

We'll get it when commoner gets it. There's an issue open there: https://github.com/reactjs/commoner/issues/64
