Bootstrap css styles

- change branch to 3.0.0-wip
- did what is specified in style guide
- issues appeared in the style guide are not solved
I left it like that on purpose actually. Because the font size is not right (which is still the issue). If the font size (or the container's height) is changed, the top of red label and the input box on the left should be on the same line. (pic below is from the style guide)

-- I'll still move the red label to the center now. :)
