Title: firefox: add an option to build with debugging enabled.

This was useful in filing a [bug report](https://bugzilla.mozilla.org/show_bug.cgi?id=923889) so I thought I'd share.

Would it be better to change the derivation names from "firefox" to "firefox-debug", "xulrunner" to "xulrunner-debug", etc, when this is enabled?
