JSON madness

I spent a little time this afternoon writing out a draft reference document for the nsIJSON interface.  If you know stuff about this interface, you should give it a look and see where things need help.  In particular, I’ve yet to quite figure out what the whitelist and optFilter parameters are used for exactly, so they’re stubby.

Addendum: Turns out the whitelist and optFilter parameters may be going away soon; I should know soon.
