Live in the system tray instead of the taskbar, bump to 0.1.14

- A tray icon (the app icon) is there for as long as wIRC runs. Left click hides
  or shows every wIRC window; right click has Show wIRC, Hide wIRC and Exit. Exit
  disconnects every server and quits.
- No wIRC window has a taskbar button. Each window is given a hidden owner window
  through JNA, because Window.Type.UTILITY can't be set after Compose builds the
  window and would take wIRC main's minimize button away.
- Minimizing any window hides all of them to the tray. Showing them again puts
  each one back where it was. Hidden windows stay connected and keep filling their
  buffers. Closing a window with X works the same as before.
