On removing bots worse than SittingDuck

1. not downloadable opponents are not a problem, as we have rather archive or no one could publish a score about it. Therefore I think we should keep every bot as much as possible, unless we can't find any valid link for it.
2. A separate rumble for worst bots is completely different from competing together, unless we copy all the normal rumble bots to the worst bots rumble as well, which is a even more waste.
3. Even if the history APS is losing its value anyway, it does so slowly, therefore it's not a big problem. But removing a lot bot all at once is a BIG PROBLEM.

This only happens when no one that runs roborumble has access to those bots. And the real problem is our priority battle algorithm — it takes more than 3000 battles to be guaranteed to have a full pairings, but the default battles threshold is 2000, which leaves new bots typically with missing pairings.
Unstable rankings has nothing to do with those inaccessable bots.
I suggest we tweak the priority battle algorithm a little — when there's no one that has battles below threshold, prioritizing on pairings. Only when everyone has full pairings, run random battles.
However, the first problem to solve is that we make sure every bot is accessible to everyone.
The literumnle already does this. However the delay between generating the priority battles and the client running them and uploading them means that many are run twice.
