Include the color config for mako from ~/.local/state/mako/style instead
of hardcoding it or templating it into the config file.
This means we have to ensure the directory and file exist before running
mako which we do with an `env.d` startup script.
Added strings which signify to flavours that it should insert
its theme color template in-between. Since the file is not
symlinked but *moved* to the config dir (through being
designated as 'template' in dotter), any future changes
should not reflect back into the repository.
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.
Since the existing wayland module basically describes everything about
my 'desktop environment' setup already anyway, might as well rename it
accordingly. Additionally, mako is important for notifications in this
environment so it moves here as well.
