CSS changes

Day in sidebar no longer automatically opened
Sidebar padding
Fixed GA tracking
JS conceptual tests concluded

The checkboxes now know what day they belong to
Can iterate over all events, and pull out data with JSON.
Bit closer to filtering

JS now sets filter variables on checkbox change, calls filter function
Filter function loops over everything, but doesn't work quite right

Events now have correct JSON, instead of teh placeholder.
Times now only have hours, the 00 for minutes was useless.
