#41341

This got changed for i18n in !12480, however, I forgot to understand
that the meaning of the graphs changed in !12378. This corrects the
behaviour.

Earlier, this was part of another MR, but that got split. Didn't pick
that commit, as there were many merge conflicts. Vim macros seemed faster.

Being the good boyscouts, but mainly because of [the comment in the
review](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/12378#note_33302115)
the words used for classes and variables are changed to not use builds
anymore.

Replace "builds" in project settings

Replace "builds" in admin area

Labels Commits and Continuous Integration graphs now scales if on
mobile.
