Add UI touches for sport events

[pluscubed]

They seem to all follow the same format in the calendar, e.g.

GGolf vs. Los Altos
GVTennis vs. Sacred Heart Prep
FS|VFball vs. North Salinas
BWpolo vs. Homestead (Scrimmage)
GVball vs. Willow Glen
GWpolo @ Palo Alto
GTennis vs. Gunn

We can parse it (e.g. Vball, Wpolo, Tennis) and display the correct icon. If we're fancy we can change the color according to Boys or Girls. If we're really fancy we can show whether it's Home or Away.
