Very little visual changes:
* class `labelled` is not used in CSS, removed from elements
* `margin-right: 0;` in `#git-graph-container .color-buttons` wasn't doing anything
* `width: 100%;` in `#git-graph-container #rev-container` and `#git-graph-container #rev-list` wasn't doing anything
(Checked on both desktop and mobile screens.)
* the now unused class `color-buttons` is left for now because it might come useful later. The button coloring is broken here and I would like to touch it separately
* removed `font-size: 80%;` from dates to ensure proper readability, it wasn't saving much space but was inconvenient to look at because other dates in the UI are normal sized
* the small size of branch labels are left as is for now because removing `small` breaks alignment, and this is a cleanup PR
So, the only visual change is date sizes, other than that there's just styling code removed.

Ran most of the Less files through the Less compiler and Prettier and
then followed up with a round of manual fixes.
The Less compiler had unfortunately stripped all `//` style comments
that I had to restore (It did preserve `/* */` comments). Other fixes
include duplicate selector removal which were revealed after the
transpilation and which weren't caught by stylelint before but now are.
