Standardize game time to start at -90 seconds
Highlight intensity based on mag of value change

ie - if a hero gets 5 kills within 15 seconds, it will be strongly
highlighted, whereas getting 1 kill it will be a more muted highlight
This effect is applied to level, kills, deaths, assists, gold, last
hits, and denies (not gpm or xpm)
Lighten scoreboard highlighting
Change gold xp graph colors to yellow
Condense scoreboard table
Fix slider label and add responsive classes
2 layouts (4x1 and 2x2) working desktop and mobile

Added a browser selector to make mobile-specific rules (e.g. a negative
margin to force the table and graph to layout horizontally adjacent to
the map and eventlog, respectively). Moved most styles from html to the
matches.css file, which needs refactoring!
