Release/0.1.0 beta

This release will have to be subject to a lot of testing before being deployed. It switches from using API version 0.4 to the next release (probably 0.5.0-beta).
I didn't implement it yet, because I wanted to discuss it first.

I would like to browse through my history by using the URL /q/:query , because it's faster to navigate to then /search/:q . To retain backwards compatibility ánd have a consistent URL, I want to reroute /search/:query to /q/:query .

What do you think of this idea?
