removed selectors that dont exist any more

Made a script to check if the selector completions for twitter bootstarp 3 was up to date. This is the part that is old/don't exist. 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.
