A slightly improved version of curseradio.

This release is an improved version of the forked curseradio. It includes customization options like status bar, cursor, and message text colors as well as key bindings. It adds vi-like keys to the default configuration, moves settings to a convenient configs.json file and fixes some minor annoyance. That includes correct clearing of the background (it's black now, independent of the color scheme of the user's terminal) and removal of the the curses cursor. Future additions are summarized in TODO.md.

In addition to these UI-related things, unnecessary dependencies are removed to clean the code up (e.g. configparser).
