Title: mostly docs + made onRender asynchronous

Important: with this merge, the behavior of the server side onRender widget method has changed.
This method is now asynchronous, and gets passed a callback function that you must call to tell feather to continue the parsing process. This will be a breaking change for any applications that currently make use of onRender methods, but will be a very fix. Make note of this when upgrading (this will only apply when using v0.3.x and above of feather)...

This was a simple change and enables a number of asynchronous data fetching/templating scenarios during the initial parsing process. I've incorporated an example usage in the Hello Feather markdown doc as well.
