Import to new git repository
The old repository was using almost 100mb of space because of all the unnecessary files in the history. So I've imported the code to a new git repository. Unfortunately the history isn't viewable from this repository anymore. To see what happened with LibreJS before 2015, see the old Bazaar repo here: http://bzr.savannah.gnu.org/lh/librejs/
