Display all languages in the contest in teaminterface

[vmcj]

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

Let me play around with such a situation.

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

I think it's crowded but not much worse than with displaying all the problems. Labels are terrible mostly as I generated the import file.

I also tried this:

which works under the condition that there are more than 25 problems, and picks the shortest list of either the problems allowed or not allowed. This only makes the problem happens less but in case you have 52 problems with a language being allowed for 26 problems (and not for the other 26) it would still be crowded.

I'm aware of the issue with C not having a problem, in case we want the option I described above I can fix it.

The last alternative (which I think is the worst):
