Merge branch 'master' of https://github.com/supertuxkart/stk-code into lapnumber
Merge branch 'lapnumber' of https://github.com/konstin/stk-code into konstin-lapnumber
Changed default number of laps to be 3 (and not the number of laps
used last time), which seems to be a better default. Some minor
cosmetic changes.
Merge branch 'konstin-lapnumber'
