Adjusted script and ladderlog setting values

Modified some aspects of the script variables for simpler understanding.
As well with enabling the ladderlog settings ROUND_FINISHED and
ROUND_STARTED
Modified some messages to make them look like a console entry. Also
removed unnecessary code from various parts of the script since they are
not needed.

Added ROUND_STARTED to output the top 3 racing best times/ranks to
everyone.
Added ROUND_FINISHED to output the relative rank position of individual
players.
Added console showing of loading of map at the start of each race.
Added the sorting of ranks by their times; lowest to highest.
Added COLLAPSE_ALL command to vanish all zones when KILL_ALL is
executed.
