Slack: Show force push on any branch

[bkeepers]

The default settings only show commits pushed to master. The /github subscribe owner/repo commits:all will show all commits pushed to any branch. I could imagine a scenario where a team might want to see any commits that were _force-pushed_ to any branch.

We should consider adding something like commits:forced

It may be a better idea for it to be configured in such a way to only show force-pushes on certain branches, not all. In my org, people are rebasing and force-pushing to their branches all the time and that would only create noise.

We like to see only non-force-push commits on other people's branches since we're relatively small, so I imagine the following may be an all-inclusive configuration:

commits -> commits on default branch
commits:all -> commits on all branches (**excludes force-pushes--the current version shows force-pushes**)
commits:<branch> -> commits on certain branches, there can be multiple of these or comma-separated?
commits:forced -> force-pushes on default branch
commits:forced:all -> force-pushes on all branches
commits:forced:<branch> -> force-pushes on certain branches, there can be multiple of these or comma-separated?

:<branch> ones are not necessarily useful in the use-case I described, but I imagine others would find it useful.
