tags can now be used

filldb: Year and Genre will be read from MP3/ID3 tags and added as Tags.
client: Tags can (and will) be displayed in the status bar.
client: StatusBar text can be configured via ~/.config/musicdb-client/config_gui.toml
client: Added a proper default config file at src/config_gui.toml
        (note: this is in src/ so that include_bytes! can use a path without /, so it will compile on windows)
client: users will need to add the new `[text]` section to their gui_config.toml!
