In preparation for at some point leaving flavours in favour of tinty
(since flavours is not maintained anymore), started preparing a rough
translation of the config file for the new program. One of the things I
changed (to make more semantic sense) is the zathura colorscheme file
name.
Switching from my custom, brittle, styling implementation `styler` to
the wonder `flavours` program which does exactly the same only with more
clarity, faster and - I would presume - more stable.
