mpd uses some additional files to work, such as pid_file, state_file, db_file, etc. when running mpd as non-root user, it is often that those files end in ~/.mpd in that case, we end up with 2 entries in a user's home, .mpdconf and .mpd - which clutters homedirs. this patch allows ~/.mpd/mpd.conf as an alternative to ~/.mpdconf, allowing for a cleaner homedir
