Use jsxc instead of commoner

Noticed several bug reports in the past few days on IRC. Still think commoner is the wrong tool for this job and jsxc is the right one.

Test plan: tested jsxc using the normal test plan. Ran bin/jsx, behaved same as jsxc
You need to provide usage yourself. It does describe all of the options. I wanted to put some common use cases in here to make the tool more usable.
