First sh*tting, now sitting

In this update, waifus can now sit on the couch and (pretend to) watch the TV to fill their fun meter.

other changes:

- fixed a bug where waifus would attempt to random roam when they weren't supposed to

- removed zombies mode. marin and komi are now unlocked in the school.

I haven't tested this update outside of the engine itself due to lack of time, so if you find any bugs please let me know :)
