[Feature request] Show only the diff of the selected file in tree

Hide all other files, respectively. This behavior is more familiar to users who have switched to Github from Bitbucket.

This is a good idea and I would love to have it myself. Since this is not what GitHub users expect, this could be implemented behind an option flag which is off by default.

If anyone wants to submit a PR for this, I would love to review it for the next version(s).

@Katarn I'm wondering if you'd like to give my implementation a try and give any feedback. You'll need to build it and load the extension unpacked and then enable it via the extensions popup menu.
