Move i18n out of latest angular.js - my error

Mea culpa, I included i18n strings in
https://github.com/cdnjs/cdnjs/commit/97a5d559150d644d6cde4aaf285d253933
6b5e1e where they should actually be in angular-i18n instead. This
commit rectifies the error.

Removed from angular.js, added to angular-i18n and min’d. Commit
includes deletions: deleted files were committed for around 15 minutes
and i18n files don’t appear to have been included in previous versions
of angular.js, so almost zero risk.
