feat!: add support for configuration file

I've dropped support for environment variables in favor of a config
file. This was motivated by

https://github.com/Cloudef/bemenu/issues/15

From what I think of environment variables, they're meant to be used
when they won't change often, especially not during a live session while
you're working. I don't think that performing a relogin to change colors
in a dmenu program is a sensible thing. Sure, you can create wrapper
scripts and place them in your `$PATH` but that feels like an inferior
solution compared to config file kept in `$XDG_CONFIG_HOME`.
