ToME: the Tales of Maj'Eyal

While creating one of my ten million test characters, I accidentally made one in the realtime example module instead of ToME. This resulted in an endless black screen and required a force quit. Fixing the example module would be good, but better would be to simply load the ToME module by default. Add an option (defaulting to off) to let the player select a module at startup for the tiny fraction of T-engine users tinkering with other modules.

You can delete the example module folders and they'll never show up.

If only one module is present it will now auto select it, and example modules will only show with cheat mode
