Add multilungual values for free text fields

[borsna]

Make al fields like label, description etc translatable

Would this refer to DDI element translation (e.g. description) or it refers to the actual variable description (e.g. label)?
The first is doable, the second I guess is the user's responsibility to add a new sibling element using a different xml:lang attribute.

@dusadrian: I think the easiest way for the user to navigate this is having some kind of global top level language switch that switches the language in all inputs in the interface but also some kind of per-field switch/compare so it will be easier to see and edit the value in parallel.
I would imagine the user interface to have to behave something like the fields in this mockup:

There would be some kind of user config to defined what languages to have enabled.

Multilinguality for display labels for the fields should also be handled but this would be another issue
