Translation Does not Support Simultaneously editing of Multiple Users

[bliles]

Describe the bug
If multiple users try to edit translations for the same document, they will overwrite each others changes since Decap groups changes to a document and all translations together. To duplicate, have a multi language setup for Decap, have two users start editing different language translations for the same page. Each time the users save, they will overwrite changes made by the other translator. It should at least be configurable for Decap to treat each translation of a document as a separate instead of always saving the original document and all translations from the browser state.

To Reproduce
Have two users log in to Decap and start editing different translations of the same document simultaneously.

Expected behavior
Pull requests should contain only the actively edited file/translation, or it should be possible to configure Decap to support multiple active translators.
