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/
