Separating lists of known words by language?

[ttasovac]

Related to #365, spell-check's "Add to known words" option will save all these words, regardless of the current locale, somewhere — and the user has access to this flat list in spell-check's settings. But if you work with multiple languages, it would be far better (and in sync with hunspell practices) to add each exception to the personal dictionary for the given language.

Is this something that could be achieved? I would be most grateful for any pointers.
