#27 Multiple windows opening on load state

[Phantom X]

Everytime I'm loading state with F3, a new window is opening with the state update, the parent window gets black.
The keyboard don't works in the new window, but works on parent, if I press F3 again, a third window opens.
If I close the windows, the parent window freezes.

Launching the state file calls LoadPlugins() which calls Shutdown and then Init, however Close is not called. Close is the method that closes down any existing window.

Ideally we need to track the plugin state (i.e. Init, Open, Close, Shutdown) so that we can manage this a little better.
