Allows users to toggle the showed diff, between individual commits and the full revision

I love this, very elegant solution for showing individual commits without needing to go to a different view.

• it’s weird that the base commit id doesn’t have a hover state. don’t have a good solution for it either.
• related to this it’s also weird that we now have a global-none class, also not sure how to solve this properly
• now that the commit selector influences the file section below, it doesn’t make sense that the “Collapse all” button also collapses the commit selector
• the collapsed/expanded state should probably reset when toggling between commits
• the hover states that have a background color should have a bit more padding

Rebase, extract some functions out of the components and address feedback by rudolfs.

Didn’t tackle the style issues since we need to figure them first out with @daniel
