Add a replicant option

[scottmc]

Add a feature that allows for making a replicant out of the Calendar perhaps with item(s) from that day's schedule listed under a small calendar/week/day view.

I cropped this out of image from the layout improvement issue. I picture the replicant to look similar to this:

Show the current month, as some will find it handy to just be able to glance that the calendar as they work on other things. Highlight the current day. Allow for picking a different day/month. Show the next event or two for the currently selected day.

Make it simple but handy.
