add selectors that seems to be missing

Made a script to check if the selector completions for twitter bootstarp 3 was up to date. This is the part that is should be added. I wrote this script to make the diff https://gist.github.com/victorhaggqvist/9b709cdb19b162a09ca0
I did cross-check a bunch of the selectors manualy and it seems to be correct.

Sorry about messing up the somewhat grouping that was, but no one should really read this any way. If you want any sorting I would suggest alphabetically instread.
