This one is a minor release. No new config options.

There are three small(-ish) changes:

• Readable names in diffs (I changed some of these last release but didn't get all of them)
• Treeview paths now have clickable links for each folder, so you can jump to any parent directory easily
• Ref icons appear in more places by commit titles

I wouldn't normally do a release this small, but I'm planning on making some major changes to the way templates work (internally, not really much difference visible to users), which is a change that could potentially take a while, so I wanted to get these fixes out and released before I started anything.
