Subject: load basic config file from ~/.mtui/config.json

This is basically just a stub for now, but you can specify
what playlists you want open when mtui is called without any
provided directories/playlists in "defaultPlaylists'!

Also comes with complementary --config-file and
--skip-config-file arguments.
