Add a calendar

[niccokunzmann]

We can add a calendar to the website which shows all our events together in one.

Implementation ideas:

1. I started at https://github.com/Brandenburger-Maker/calendar-federation/ to build the calendar specification. This allows one joint calendar.
2. If we add the calendar links and entries to the labs, we can generate the joint calendar but also show a separate calendar on each lab page. Would that be a use-case?

Sounds good! I have created "https://offene-werkstaetten-brandenburg.de/veranstaltungen" and erased the calender on the main page. I think it's better for testing. This is the url of the calendar of the FabLab Cottbus: webcal://blog.fablab-cottbus.de/?plugin=all-in-one-event-calendar&controller=ai1ec_exporter_controller&action=export_events&no_html=true

It would be nice to categorize the events by the town / lokal area. I think it's more helpful for our users

Would it be ok to give each source a different color?

For the categorization? Or as another way to make a distinction?
