Show commits behind/ahead

[tyhrstan]

The feature request

It would be great if it would be possible to see how many commits a branch is ahead or behind.

Proposed solution

On the web when selecting a branch it shows the amound of commits ahead or behind. A similar information box in the desktop client would be great so you can instantly see if your branch is behind the root.

Thanks for the issue @tyhrstan, I'm going to roll this into #8048 where we are tracking enhancements to the branch list.

For reference you can go to History > Select Branch to compare to see the ahead/behind counts.
