Make the meaning behind the people numbers more clear

[nishoof]

Feedback from a playtest :o

It says in the instructions that 1 -> 2 means there is a person at floor 1 that wants to go to floor 2.

It's not very clear though that the numbers under the elevator mean the floors that people in the elevator want to go to.

Some possible fixes:

1. Maybe could have some animation from the queue to the area under the buttons to indicate that a person was picked up. Would be pretty hard though, prob not worth it since it might not even indicate it well enough.
2. Keep the arrow syntax (1 -> 2 instead of just 2). Would take up a lot of space though.
3. Maybe just have some text, like Deliver to: 3, 2, 2 instead of just 3, 2, 2.
