API to get all string translations

[nijel]

Describe the problem

There is no way to get all the translated units for a source unit in the API.

Describe the solution you would like

Introduce an additional endpoint for unit (tentatively /api/units/(int: id)/translations/) that would work for source units only and would include links to all the translation units.

Describe alternatives you have considered

I was also considering including this directly in the unit serializer, but I think this would ruin the unit listing performance, or we would have to use a different serializer for listing and details. That is certainly a viable approach as well.
