1.13 Update

Minor update for a common issue: KBonk's default behaviour was to minimize to the system tray. This wasn't clear, so it was causing confusion and giving an unhelpful error message when one would try to re-open it (because the port was already in use by the existing instance!)

The changes are as follows:

• New Setting: Minimize To System Tray.
  • Defaults to disabled. 
• Attempting to open a new instance of KBonk while it is already running will now focus the existing instance instead.
• Added an error status for if the Browser Source port is in use.
• Executable should now properly display its icon in the explorer.
