TITANIC: allow loading saved games via the GMM in the main game window

[dafioram]

In case the user accidentally hit start instead of load it would be nice if they could load a saved game from that point using the GMM.

main game window gmm open

If I open the GMM while the titanic logo is being shown or once it reaches the main game window the game crashes. I would like to be able to load using the GMM when at the main game window.

The bug was fixed, but now the game is back to how it was before the feature was requested. It has the load option not selectable when at the main game window (see the picture).

I would like to be able to load using the GMM when at the main game window.
