Add Enable IntroDB submission

[Fuzzythegoatq]

Describe your suggested feature

You have to implement your introdb api key for this to work

Shows a button to submit intro/outro timestamps to the community database. Via video player (Optional)

Would like this added so I can implement a introdb submission within cloudstream
