In the end it should function more or less the same as the CSRBot, but I'm still not sure that the CSRBot is where I want it to be.

Looks good, the code using `PullRequestPoller` turned out much nicer 👍

I feel like I'm always comment on naming, feel free to ignore such suggestions, they are just suggestions 😃 In this case I would have renamed `PullRequestPoller.lastBatchHandled` to `PullRequestPoller.ignore(List<PullRequest> prs)` and the bots would typically call `poller.ignore(prs);`
