From 793860dbd6df42d5bbf05542f2292a1c6d30fc76 Mon Sep 17 00:00:00 2001

Subject: style: replace hardcoded color codes with css variables

In order to: a) do custom theme simpler by just replacing necessary
vars, b) apply this theme to filters as well; the main cgit.css file now
defines CSS vars and uses them in color parameters.
