Dalekfile is undocumented

[stuartlangridge]

How to make a Dalekfile is pretty much undocumented. In particular:

1. it's not clear that a config file can even exist, nor what it should be called or where stored
2. it's not clear without rtfs that it can be json, yaml, js, or a bunch of other formats
3. Lots of the docs link to non-existent docs for the Dalekfile, for example http://dalekjs.com/docs/chrome.html which links to http://dalekjs.com/pages/config.html which does not exist.
4. The top-level options available in a Dalekfile are not documented anywhere
5. The options available to configure sub-projects like the chrome driver are not documented on the Chrome docs page

Yep,

Documentation, the developers weakest point :D
No seriously, the situation is bad & due to my limited time I always postponed this.
If you think you could contribute something, we could talk on IRC about how to manage this.
