sheriff-bot should be able to do multi-revision rollouts

[Gabor Rapcsanyi]

The sheriff-bot should be able to do multi-revision rollouts.
The webkit-patch is ready for this after https://bugs.webkit.org/show_bug.cgi?id=33336

Eg.:
  sheriffbot rollout r123 r124 r125 Some reason

Needs another round. :)

Please split this (arg parsing, etc.) into private (_foo()) helper functions instead of just making execute longer.

Um, why do str(int(?

Please pass them individually as numbers converted to strings, instead of as a joined string.

Here I just check the revisions whether they are numbers and after I convert back to string for the concatenation.

We have to pass the revisions between apostrophes or quotes to webkit-patch, and I think that's the best place to convert them to that format.
