Full update to latest state of main.json including Dutch translation updates. Validated with JSONLint.

Yeah, there was a large backlog to overcome.

Hi, thanks for your contribution!
If you haven't already done so, could you please make sure you sign our CLA (https://jitsi.org/icla for individuals and https://jitsi.org/ccla for corporations)? We would unfortunately be unable to merge your patch unless we have that piece :(.

Lint is failing, I think just the empty line at the end of the file needs to be removed.

Lint is failing, I think just the empty line at the end of the file needs to be removed.

The extra line is introduced when I select the whole file and then paste in the full file I had been working on offline.
It happens with other projects as well and sometimes I forget to remove it.
