FlexFlyout v0.7.0

Added

• Titles in scripts the flyout's own fonts lack (Korean, Chinese, Thai…)
  show in the system's fonts instead of as empty boxes.
• The mouse wheel over the volume bar changes the volume (2% a notch).
• The tray icon's tooltip shows the playing track.
• appearance.theme = "system" ("Same as the system" in the settings
  window) follows the system's light or dark mode, also when it changes.
• general.show_over_fullscreen (on by default): turned off, the flyout
  no longer comes up by itself over a full-screen game or video on its
  monitor.
• KDE Plasma: the volume and media keys show the flyout, also at 0% and
  100% volume.

Changed

• The previous run's log is kept as flexflyout-previous.log. A log that
  cannot be written no longer stops FlexFlyout from starting.
• Linux: when FlexFlyout cannot start (GNOME, X11), it says why in a
  notification.

Fixed

• Starting FlexFlyout again while it runs opens the settings window
  instead of starting a second copy.
• The tray icon no longer goes missing when FlexFlyout starts before the
  taskbar or the panel (at login).
• KDE Plasma: monitor = "primary" (the default) now uses Plasma's
  primary screen; it used the screen under the mouse pointer.
• Linux: the volume is followed again after PipeWire or PulseAudio
  restarts.
• Linux: the volume bar keeps the balance between left and right.
• Linux: cover art from the web (Spotify) no longer delays the flyout of
  a new track.
• Linux: Plasma's volume popup, when hidden, comes back also when
  FlexFlyout is ended by a signal (at logout, kill, Ctrl+C).
• Windows: a track that Media Player is still setting up no longer shows
  as "nothing playing" first.
• The update check tries again within an hour when it gets no answer.
