frontend: added possibility to see the already played matches on the "create simple" page
added "ticker" graphs to the index page which enable comparing different chances as the tournament is played
aesthetically improved starting page; added market value to ticker
frontend: always show every team in the group phase (even if 0 points)
frontend: visually improved X axis labels in ticker
backend: clear QLess job data when results have been parsed

The jobs (with all the data) were still kept around forever, even if they are not needed. This puts an unnecessary strain on the database.
