Suggested log improvements

From DXV:

think the log could be way more readable. - use "+$9" rather than "takes 9 coins" (and -"$9") - use a symbol for crown, if you can't make an ASCII crown or just "C" (and similar "+9C") - colorcode player names - put parentheticals in a darker gray to more easily ignore them - drop the word "zone" - indent for side-effects of visiting a zone or playing/scoring cards (thus sometimes multi-indenting)
