This commit adds a set of templates for the calendar month block, and
the events filter. The same data exporters used in the main calendar
view are utilised and the same logic.
Some additional data was added to the exporters, and in the long term
this will be used in the main monthly view so I did not feel it was
prudent to strip it out into a different view of the model.
