Add an option to show all refs of a commit in the log

What steps will reproduce the problem?

1. Create a Git repo.
2. Make some commits.
3. Go to "View Logs".

What is the expected output? What do you see instead?

The "Show Log" window shows only branches, tags, remote branches, and a few special branches for each commit. However, the user sometimes would like to see special refs, such as refs/original/* and refs/notes/*, listed. It would be nice if there is an additional option for such feature.

What version of TortoiseGit and Git are you using? On what operating system?

TortoiseGit 2.5.0.0, git version 2.14.1.windows.1
