[API Request] Option to add specific keys to multi request

[LuziferSenpai]

Hey,

it would be nice if we could add keys from the result entry, to the /api/mods endpoint, but with a queryparameter.

So as a user you would add for example: keylist=name,owner,summary,title,thumbnail,tags and it would ONLY give these keys back.
With that we can also get more information that would be needed eventually, without calling each mod's short or long information, which would increase api calls.

Greetz,

Luzifer
