Collapsing folders currently just throws a console error

This PR fixes this and allows folders to be collapsed again.
Also:
- better cursor interaction with folders
- added some color to the diff detail stats
- remove green link color from all the file names

- Replace all default exports with named exports, except for Vue SFCs
- Remove names from Vue SFCs, they are automatically inferred from the
filename
- Misc whitespace-related tweaks
This PR adds a filetree to the left side of the files/diff view.
Initially the filetree will not be shown and may be shown via a new
"Show file tree" button.
Showing and hiding is using the same icon as github. Folders are
collapsible. On small devices (max-width 991 PX) the file tree will be
hidden.
