Final changes before 1.0.0

Created by: indexzero

@yawnt found a few minor things when I was using this extensively:

• EventEmitter3 will not throw on an unhandled error: but without any default handler it's very confusing to debug when your proxy logic is just plain wrong. We should have a default logger if there are no error handlers. cc/ @3rd-Eden
• We should have a simple(r) .createProxy() method: which is basically just exposing createRightProxy. A lot of our users don't even bother with httpProxy.createServer, they just use new httpProxy.RoutingProxy(). Forcing them to create a server that they will never use feels very awkward.
• Remove all (soon to be old) caronte links: The README.md and a few other doc links still have hrefs to the caronte branch
