Fixing bug with bootstrap-sass.

Newer versions of bootstrap-sass-official are not compatible with the version of sass used in this project as it includes changes to the way division works. This issue is documented in these issues; twbs/bootstrap-sass#1231 and twbs/bootstrap-sass#1230. Making the version of bootstrap-sass required more specific stops the breaking upgrade.
