A GUISheet can assign its field "loadAlong" any strings designating other sheets that have to be loaded as well.
Implemented this for all menus sheets as I see fit (load the whole MainMenu, but don't load MainMenu or Settings for the InGameMenu).
This is just a measure to avoid lags when clicking through the menus.
