* Make repository file list useable on mobile
- When you're browsing a repository on mobile, you're met by a giant
block called the "repository file list". The current design is not
useable for mobile and is a big annoyance while browsing a repo on
mobile. This PR removes that annoyance by making it more suitable design
when on mobile.
- Adds HTML for the commit/file time to align it vertically(noticeable
on mobile, not on PC).
- Show all information horizontally and not vertically.
- Remove the last commit message of the file, there isn't enough space
on mobile to place this anywhere, so we're not trying to make a
best-effort here and instead just not display it.
* Remove unnecessary `!important`
* Fix broken HTML
* Simplify code
