Changes

** The l10n translations for the next release will be kept in the patch queue until it tagged for building and it s branch for the regluar fixes has been checked in.

** '''frg''' tries to add support for later javascript syntax features in a separate wip patch queue. Progressing nicely and at the start of 67a1 now.

** Builds from this branch are not very usable right now becusase the preliminary support for optional chaning and regexp needed to be removed for a full rebase later.

*** Missing support for dynamic import, big int and private class fields are the top issues which need to be addressed.
