Switch back to Babel 6

[tricoder42]

Upgrading to Babel 7 is backward-incompatible change and requires project to update to Babel 7 as well. This causes several bugs when using Babel 6, eg. #171.

Since Babel 7 is still in beta, js-lingui 2.x will use Babel 6 and new version 3.x will use Babel 7. These two releases will coexist in parallel for some time.

Hey @tricoder42 I see this has been open for a bit with failing tests. Is there something I can help out with to move this forward?

[tricoder42]

@adamgruber Sorry for delay. Yeah, I'm having trouble to configure babel/rollup. For some reason, transform-runtime imports aren't wrapped in _interopRequireDefault which causes errors. Do you have any experience with this?

[tricoder42]

@adamgruber Problem seems to be solved with a simple rollup config. I'm waiting for the tests (green locally) and then I'll proceed with release.

It looks like that it can be released.

I know... I really don't want to screw this up, because it's potentially backward incompatible release for all those using Babel 7 beta. I would like to release 3.0-beta right after, but I don't have release process ready. I guess I'm gonna ship this pig tonight and 3.0-beta soon.

Thank you for patience!

Released in 2.1.0, thanks everyone for patience!
