Autofill language

It would be great if the language search field would be auto filled with the language the actual file uses. (based on the file extension e.g.)

So if you currently edit a .js file it should automatically fill in javascript in this box.

This feature already exists but I checked and apparently there's a bug because the setting is gone in the latest version. Probably due to an API update.

Ah okay. didn't know that...

I wanted to help fix this, but I don't truly understand what's fully going on. However, this seems to be the cause (I suspect):

'ask-stack.autoDetectLanguage' could not set the default. Attempted default: undefined; Schema: true
