Visual indication of approved commits (BB-6179)

Hi

I want to review all commits on my repository. I click on a commit and once I reviewed it I press "Aprrove". This is great but I would like two enhancements to it:

• When I am on a commits tab I don't see which commits I've reviewed and which not. It would be nice to add some flag/icon/color indication to the approved commits
• When I am looking in the commit page I'd like to quickly skip to next/previous commit in a list. Jira style "j/k" shortcuts would be great for this. (and maybe arrow icons too for those who don't use shortcuts)

Thanks
Dusan
