Github API Pagination breaks comment detection

[jsuereth]

Github paginates reponse lists. Although we upped the per_page size to 11... err 100, we can't be sure that this solves the whole problem. We should update the Github API so that we can read all results rather than just the first page.

Note: Probably easiest to make some kind of buffering/blocking collection for now...

Note to self: @adriaanm Your fixes make this on less likely needed in the future
