Add debug module and messages

[daffl]

Add the debug module and debug messages for feathers core (and probably all official plugins, too). Because it is super helpful and easy to use.

You mind if we leave this open? I'd like to add documentation for this in the readme.

[daffl]

Can you open another issue or PR? Should it look like http://expressjs.com/guide/debugging.html?

[marshallswain]

Yeah. Thanks for showing me that. I'll see if I notice anything else that needs to be in it.

[daffl]

I would say for now it should just be a point in the FAQ at https://github.com/feathersjs/feathers/blob/gh-pages/faq.md until we figure out what the new website is going to look like.

[marshallswain]

Sounds good. Just a list of available debug options with a basic example of how to turn them on/exclude some should be enough I think.
