Reformatting LV game schedules.

Move LeagueVine parsing for each section into its own function.  No
more double-duty.
Displaying the schedule now sorts by game day/time and groups games at
the same time (chronological listing).
Also display field info (if provided by LV).
Reformatting current LeagueVine games.

Larger text size for current games.
Also color-code winners and losers.
TODO: Perhaps differentiate between big wins and small leads by shading
the colors on an RGB scale.
