Some adjustments on the engine - time consumption

There were some minor problems in the engine, regarding the time consumption of Special team plays.

This is the way we will handle it for all matches with kickoff later than 2011-09-30 00:00

Fieldgoals: The clock is running

Punts: The clock is running

Kickoffs: The clock is running on the catch of the kick returner

PATs: no clock

At the same time we found a small issue with the playclock in overtime. Sometimes there was a reset to 0:00. This was fixed.

Since both things don't add anything / don't change the behavior of the gameplay, we are activating this u p d a t e midseason - without asking our community. We hope you agree on this.
