Calendar colors now handled through html datasets.

Previously css rules for each calendar (governing color) where handled
through CSS classes. This however had the problem that all calendar
names needed to be mapped unto valid classnames, and it brought some
problems with updating it.

This change places the calendar information in the dataset.calendar
attribute. It's still base64 encoded, so special characters don't need
escaping, and XML doesn't trip up.
