Fix for issue #3

[PatrickG]

If a request is executed before a connection exists, save this temporarily and send it after a connection has been established.

[funston]

feels like a pretty big fail in the library that it doesn't either:

1. let the client know when a connect happens
2. buffer any shout/requests internally in speaker.js until it has

asking us to do a settimeout or other hacks is silly.

I've found a better module: axon (https://github.com/visionmedia/axon).
I've not tested it yet, but the docs are looking very nice.
