node-ready model

[matthewmueller]

Lots of changes here - perhaps this is more of a show-and-tell. Basically gives model:

• async plugin support
• abstracted out transport layer based on the existing methods (all, get, removeAll, save, update & remove)
• uses ForbesLindesay/is-browser to abstract out the node.js/component differences.

Really hoping for a better way to make this work with node, although @ForbesLindesay's is-browser is really clever.

Just for context, this is the sort of thing I'd like to be able to support with plugins: https://github.com/MatthewMueller/model-mongo
