Display all languages in the contest in teaminterface

Also limit the languages in case the problem has different languages.

I don't really like the [All] as it is not really true but rest is also not that good. Found this when playing around with something and needed the info so added it.

@nickygerritsen suggested this as alternative:

Or this:

I like the idea, but I would not do All, but:

• Not display any badge anywhere if we have no problem specific languages. (you already do this I think)
• Display exact problewms otherwise. So Instead of All display a badge for each problem that does not exclude it.

Yes

* Display exact problewms otherwise. So Instead of `All` display a badge for each problem that does not exclude it.

I didn't try that but thought it would be overcrowded, but I can try it.

I like adding this info in general, wonder if we need something special for too many problems (e.g. > 15) like online judges where this different languages per problem are more likely

So also if there are no specific languages per problem? I think I disagree

I think we are on the same page, I just worded it confusingly. I meant, I think the change is an improvement, but there might be the edge case that I pointed out
