Links to the source tree for each branch in new source browser

[GoogleCodeExporter]

When trying to view the source on the source viewer, I usually ended up 
clicking the project, then the branch, then the head commit, then the the tree 
link....

Sounds like a lot of clicks.... instead, install tree-links and get the link 
next to the branch.

Someone internal at Google wrote a Chrome extension to hack the DOM to do this. 
We should natively do it in the source browser templates.

I think we'll end up taking care of this as a result of issue 12.

Not a full-on rewrite as in Issue 12, but a quick update of the default commit 
view provides something of a workaround:
