This speeds up CasperJS tests by 25 seconds per main app page load.
When we switched the SockJS, the casper tests got inexplicably slower. I
finially figured out what's going on. The first SockJS XHR request (remember
that we don't get websockets in the test suite) gets considered part of the page
load and therefore the PhantomJS onLoadFinished handler doesn't get called until
the SockJS XHR finishes, which happens at the heartbeat, 25 seconds later. To
fix this, we simply don't create the SockJS object on page load since it will be
created on demand, anyway.

We've only gotten one error report for this error, and it didn't have a stack
trace, so it's hard to know whether this will actually fix the issue or not.

Without an explicit close, we will continue to get messages on the old
connection, even once we replace the _sockjs property. This leads to
"impossible" situations, such as receiving ACKs after reconnecting.

There will be browser errors on staging when this is deployed due to the socket
protocol changing.

This will hopefully help with the send dialog being stuck on
"sending" as well as allowing us to not show errors to the user on
reconnect.

Clients can only have one connection at a time, anyway, so we can
just keep track of a client id, instead. This makes reconnections
easier.
It's a little funny to use queue ids for the client id, but we know
they should exist by the time the client is connecting and they are
guaranteed to already be unique and authenticatable. We will also
eventually be integrating the event system and the socket code closer
anyway.

Previously, if the user held down the enter button while the socket
was disconnected, the client would try to connect in a very tight
loop. Now we throttle reconnection attempts to 1 per second.

If the user has a flaky connection, we might be in the backoff state
of attempting a reconnect. But when the user regains connectivity
and tries to send, we want to send the message as soon as possible.

There seems to be some sort of bug involving PhantomJS and XHR
streaming messages. When successive pages are loaded that use XHR
streaming, PhantomJS seems to think the second one never finishes
loading and therefore hangs.

Because our authentication system reads cookies from the initial
connection attempt, several SockJS transports can't be used.
