CI3 User Guide Style

We have a new style for the CodeIgniter 3 User Guide, and would love your comments on it!

The user guide can be read online or you can download it and read it offline.

Hello jlp,

First of all - the docs seem nice but there is one big problem with the navigation. The problem is you have to either scroll (the right side of the screen) or click (the explorer/navigator-like menu on the left) to find your thing. I was much less effort to find an article in the old guide (still is) because all topics were only 1 click away. This practice was a bit genius and I don't think it is the thing you should abandon when making the new docs.

Also - please - fix the captcha at the register screen. I am by no means color blind, but it took 10 refreshes to guess it correctly. That is too much. Really.
