Currently, creating recurring events is not supported
in gnome-calendar.
This patch adds a Repeat combobox with a list of
simple recurrences such as:
* Monday - Friday events
* Daily events
* Weekly events
* Monthly events
* Yearly events
and also a list of recurrence-duration-types such as:
* If an event should repeat forever
* A date until which the event should repeat
* Number of times an event should repeat
It enables the user to create simple recurring events and
even modify the recurrence-property of an already
recurring event.
