[PATCH v2a 3/3] gitk: Include commit title in branch dialog

[Rogier Goossens <goossens.rogier@gmail.com>]

Hi,

I made another branch dialog related change, included in this message.
It applies on top of my other two patches.

Rogier.

------- 8< ------------------- 8< --------------

Only the SHA1 was included. It's convenient to have the title
mentioned as well.
