Docs update for V0.3.0!

You heard it right folks :) we've finally updated the docs for V0.3.0 and I guess this also means we're officially launching this version now xD. V0.3.0 has been available from our website for a while, but it had undergone quite a bit of a change in how rendering is done, so we decided to update the docs, which actually took longer than the changes to the software. You'll see what I mean when you visit the new docs page, they've been completely re-written from scratch.
