With the added Error handling, the stability of the recurring-events-parsing section has improved as well. This is handy when using non-supported iCalendars.
This is a more thorough approach on fetching and parsing recurring events. It has been tested on Google and Yahoo iCalendar, so it might not work on others. As further testing and feedpack is required to test it's reliability, the parsing of reucrring events is switched off by default. Setting 'use_recurring_events' to 'True' activates parsing of recurring events.
