Adds new synthlore title screens, reworks title logic.

Leaving the lobby screen list empty now adds all icon states to the lobby screen list. Also, only one dmi plays at a time.

This means that adding a new title screen is now as simple as just adding it to the dmi. Or making a new dmi for a new category.

Added a new sound when you click things in the menu - more futuristic.

I wonder if it's possible to pick a different selection every time, and maybe make it possible to choose the type of title screen you want

for example i could choose the corporations selection or the synthlore selection

No, I want them to all play for now.
