Managing results/championship table: offering help :)

[c.pucher]

New version, with following changes:
- after importing a result the mandatory pitstops would always be set to 1, regardless of the set number of mandatory pitstops in the configuration

There was even a TODO comment in the code for that one. Who made all this bugs in this code in the first place anyway, sloppy lazy programmer that one :
Just in case I checked the code, no more TODO comments ;D
