Rocking Rackets

We made a few changes in the game today.

First of all, when you fire a player it cannot be re-hired for a random period of 12 to 36 hours. This is meant to stop frequent player trade.

Secondly, the surface percentage is set to a maximum of 60%. Players with a higher percentage on a surface have it cut off. This should make the game more realistic by making it impossible to have extreme specialists, though it is still possible to focus on one surface.
