update to match bootstrap v3.0.3

Update to match the latest bootstrap 3.0.3 release.

This is _my_ last update and contributing to this repository. Thank you @jlong for the trust and commit rights ;-)
In the early days I did the 1:1 sync by hand. Lastly the converter by @glebm did the main part translating the files from less to sass.

I guess for bootstrap 3.1.x there are big news if you like sass. The guys from [bootstrap-sass](https://github.com/thomas-mcdonald/bootstrap-sass) teamed up with [twbs](https://github.com/twbs/bootstrap).

The official [bootstrap-sass](https://github.com/twbs/bootstrap-sass) is here!

Happy Merry Christmas everyone! :christmas_tree: :santa: :gift:
