simplifies parameter handling in main (e.g. it's not
necessary to list and ignore parameters in the 2nd
pass, when they were handled in the first pass).
Removed some command line options for which there
is a guy (e.g. --weather), or which are not really
useful (--list-karts).
All parameters to options must now consistently be
specified using '=', e.g.: --log=1 and --kart=tux.
Also removed support for 'classic' camera (which was
not used anymore). Removed now unneccessary #include
in user_config.hpp, which made some #include changes
in other files necessary.
