For detached HEAD, include commit details in commit SHA tooltip

[chrispy-snps]

When the HEAD is detached (such as during rebase conflict resolution), currently the branch widget tooltip shows the current commit SHA:

It would be useful if the tooltip could also show the details of that commit (user, date, description):

This would be more meaningful to a writer working in a team than a bare SHA value. The same format used for the push/pull button tooltips could be used.

This would be especially useful during a multi-stage rebase resolution, as the commit SHA will step through each upstream conflicting SHA in sequence, and for the writer doing the resolution, these SHAs will be for someone else's work and not their own.

A testcase is included. The testcase uses a normal detached HEAD instead of a rebase detached HEAD for simplicity, but the enhancement should work for any detached HEAD situation.

Hi! I agree, the tooltip can offer more helpful information. I will schedule it for a future release.
