working:
• mpc control via Raspberry Pi with Adafruit display's 5 buttons
• user account control with different playlists (specified as CSV files)
• all other functionality of the original PhiPy radio

not yet working:
• weather info
• system menu for rebooting/WiFi reset
• pause button with "true" pause functionality (will require recording from the stream to continue after the pause without interruption)
• use left button to escape menu, right button to select
• moved whole main menu in a dedicated function since we need to call it in more than one situation

ToDo:
• going back from submenus still not working
• weatherInfo not tested
• move news channels into main menu
• true "pause" functionality (right now it's just "stop")
• code cleanup
