Changing the API to conform to Node.js' one

[gmarty]

We discussed that offline, but let's gather some thoughts about it. The idea would be to reuse Node.js' API for HTTP.

The learning curve would be easier for developers familiar with Node.js and also possibly reuse code already written (including Node.js unit tests!).

The Node.js API is quite complex, but maybe a subset of it would still make sense.
