From cb250d490c14872f03bb0320179e48d05fe2539d Mon Sep 17 00:00:00 2001
From: Kenneth Zhou <knthzh@gmail.com>

Subject: Basic xdg directory implementation

Search $XDG_CONFIG_HOME and $XDG_CONFIG_DIRS for config files.
This also negates the need to have separate user and global variants of
mp_find_config_file()

Closes #864, #109.
