The purpose of this library is to provide an easy way to long-poll
on a URL for events and dispatch as they come in.
I took a very low-tech approach to event handlers. Basically,
$.ev.handlers is treated as a hash that’s keyed by event.type and
contains functions that will run when events of that type come in.
