Convert Configure Screen into the Main Application Window

- What
  - Convert the config screen into the main application window
    with configuration as just one of the functionality it provides
  - Rename config screen to main window to match new designation

- Why
  - System Tray isn't available everywhere (e.g Linux)
  - This requires moving functionality into a normal window for cross-compat
