corrections
Add experimental support for multi-monitor on linux using xrandr.

Now you can play STK on one screen and watch TV on the second ;-)

Currently I use first (main) screen. We can detect from which screen STK was executed using xinerama.

Will be improved.
Rename some variables, free memory etc.
Remove debug output
Few more checks
Moved check_structure detection from center of kart to the front
of the kart (which will work better for a photo finish). Hopefully
no other side effect.
Fix #1429 (physical objects do not reset when restarting a race).
Changed return type of getIconBasename() to be a reference.
