protocol and content handlers for web services

handlers.js

/**
 * Sadly neither Chrome or Firefox fully support the functionality herein.
 * Chrome supports only registerProtocolHandler, and Firefox supports
 * a limited set of content handlers - at the moment it's pretty much
 * just RSS feeds. These do work great in the older Opera 12 though.
 * 
 * I've moved on from the abandoned Opera to Firefox but I put these
 * here for future reference, hopefully browsers implement both
 * navigator.registerProtocolHandler and navigator.registerContentHandler
 * fully in the near future.
 * 
 * NOTE: To run any of these, you must be on the same domain as the
 * handler registers for. I think this is a somewhat flawed approach,
 * but that's the approach every browser has taken thus far. So, go
 * to the domain you wish to register a handler for, open the browser's
 * inspector/console, and run the code from there.
