Detect factoid language #5
Description
Implement language detection on factoids, so they're returned in the same language as they were stored.
A simple (although limited) way is to define splitter keywords for each supported language and save those with the factoid. (e.g. "is" for English, "er" for Danish"), and then also define reply strings for each language.
For old factoids with no such metadata, maybe try a language detection to get an idea.
