Disable inclusion of information from .po header

[mcfilib]

By default gettext_i18n_rails_js dumps things like email addresses (Report-Msgid-Bugs-To and Last-Translator) and information about language teams (Language-Team). These may be pieces of information that you want to expose in the JS of public-facing, commercial, applications.

I appreciate this is something that likely needs to be addressed upstream in https://github.com/webhippie/po_to_json but I wondered if you had any thoughts as to how it might be achieved or whether you'd accept such a patch?

I'm fine with a patch that changes it, maybe including some kind of configuration to enable/disable that behavior.
