Implement a menu system

[fcheadle]

The example game, and perhaps the integration library itself, should contain a menu system that includes a main menu and a pause menu (these can be the same menu).

Does it make sense to include such a class in the integration lib?

[Thraka]

I'm not sure. It may make sense to add it to the SadConsole.Extended library.

Would it use anything from GoRogue?

No, if my Homicide Detective use case holds, this would really be done entirely sadconsole-side.

The example game should still include an example where I initialize it, to give players an idea to work from.
