Allow users to send Thanks for other photos in Explore

[misaochan]

This was inspired by #1963 , but slightly different. AFAIK, the "Thanks" mechanism already exists in Commons. Is there an API that we can use to allow users to send Thanks via the app when browsing other people's images, similar to "Nominate for deletion" for our own images? Since the framework already exists in Commons, there should be no need for server-side implementation, thus making this a possible task for stuff like the 2019 hackathon #1962 . :) @nicolas-raoul @VojtechDostal

I think before 2019 hackathon, we can make 2018 hackathon task ready for production first. Since these two tasks were very similar, I don't think "thanking" would b suitable for 2019. It would look like repetition of 2018 hackathon IMO. What do you say @misaochan ?

Wasn't the 2018 hackathon task patrolling? I wouldn't mind adding the polishing of the patrol task as an option, I think Vojtech mentioned that they want several task options though so people can choose which task they want. :)

It was voting, both patrolling and thanking. But it was a separate activity, so it can be a good idea to include this option to explore feature.

Oh, okay! So it taps into the Thank system in Commons already? In that case yeah, we can convert this task to tying it up with Explore activity.
