Support "LongText"-kind of data on Localize fields

[SkrOYC]

Fields under the "Localize" tab accept just text, which means that we can't use line breaks.

Here is an example of someone with this problem:

How to reproduce:

• Go to the Localize tab and write a multiline text on one of the fields, for example: the new "No items" that's at the bottom.
• Add a string/text with line break. Something like:

"A line.
Another one.
The third"​

• Go to any view without data to see how it's represented. Break lines are ignored, as if you were writing it on just one line. Basically, the same that would happend if you add line breaks to any Display Name
