Fix script translations problem

[antonlukin]

It seems that js script translations (for blocks) still not working.
I determined that the problem is the absence of a required wp_set_script_translations function call.

Checked this edition on the last plugin version and it works.

Thanks!

Since this 3.5.x branch still supports WP 4.1, then I think it will need the JS language files generating and adding to the /languages directory and the function call update to include the path argument. Could you add that in please?

I'm expecting this to be the last (or one of the last) 3.5.x releases and the 3.6.x branch will have a much higher version of minimum WordPress, so all of the local translation files and language path references can then be removed.

@GaryJones I have no confidence that I did everything right.

Added the latest translations from existing language packs:

Regenerate .pot file:

wp i18n make-pot . languages/co-authors-plus.pot

Update .po files from .pot:

wp i18n update-po languages/co-authors-plus.pot

Regenerate .mo files from .po files (ideally the .po files would have been translated first - I did en-GB).

wp i18n make-mo languages/

Regenerate JSON files:

wp i18n make-json languages/

@antonlukin I cherry-picked your work into a new branch and rejigged it into some new commits in #1007, which unfortunately didn't retain you as the original committer. I'd love it if you could test the current develop branch and double-check that the JS translations are working for you now.

Thank you!

I checked, everything works correctly. Thanks a lot!
