[robocup-humanoid] Time Penalties for the Goalie

I cannot remember a single game in the last years where 
an indirect or direct free kick was called against the goal 
keeper. Therefore, I expect that such situations will be very rare
or probably never occuring in 2010 also.

On the other hand, I would also expect that if a referee calls such a foul
by the goal keeper it must be a really severe foul or misconduct.
Then a hard penalty would be appropriate.

Therefore I suggest to try this rule out at local RoboCup Opens,
e.g. in Germany (April) and Japan (May), and we can
then use the experiences made there for a rule adoption
for RoboCup in Singapore in June, if it seems to be necessary
and after discussion on this mailing list.

The referees must speak loud and the robot handlers must listen and watch 
out. The referee can issue warnings and penalties to teams whose
team members and do not behave properly.

The structure of Sections 1 to 17 of the rules follows the structure
of the FIFA Rules (which does not have sections beyond 17),
please see the link to them in the left navigation menue at
http://www.tzi.de/humanoid

Therefore I suggest to keep sections 12 and 13 but to 
emphasize clearly that all indirect and direct free kicks are replaced
by time removal penalties.
(Penalty kick is, of course, conducted as usual.)

Later on in the future, when some indirect or direct free kicks
will be introduced back again we can then start about reformulation
of the specific rules for indirect and direct free kicks.

I am in favor of keeping the current structure of Sections 12 and 13
(plus more emphasize on removal penalty as replacement)
because it is closer to the FIFA rules when indirect and direct free kicks 
are called, which in our case are all (- does anyone want any 
exceptions? -) replaced by removal penalty in 2010.

Best regards,
Oskar
