Link to the Google calendar in the breadcrumbs

[inghamn]

We want the breadcrumbs on the event view to look like:
Calendars >> Commission on Aging Calendar

Where "Commission on Aging Calendar" is a link to the Google Calendar embed.

Ideally, we would always link to the original calendar, as opposed to one of the aggregations we've set up.

Most of the events on the site are collected into aggregated calendars. Because of this, the calendar for the event is usually "Government" or "Boards and Commissions". However, ideally, we'd use the original calendar for the breadcrumb, rather than the aggregated calendar.

I need to figure out some way to determine the original calendar, and link to it in the breadcrumbs.
