FEATURE REQUEST: Add clickable tree and parent SHAs

[adamhill]

A friend of mine that give talks about how git works behind the scenes (Cori Drew) to developers is wanting a way to interactively show the guts of a git commit.

Ungit works very well for this, but part their current presentation uses git cat-file -p <hash> in a shell to show the tree and parent. It would be nice to see these SHAs in the existing node details and make them clickable.

DESCRIPTION: As a user I would like to see the tree and parent SHAs in the same box as the current commit details. Like the output of git cat-file -p <hash> in the upper right, directly underneath each other.

FUNCTIONALITY:

• Display the tree and parent SHAs for a commit.
• Click on the displayed tree or parent SHA and it navigates to the correct commit.
• Would be nice to have a hot key to jump back and forth between the node you came from.
