Export: Default destination filename

[davidhedlund]

Export bring up the "Enter Destination Filename" text field. The default destination filename is set to what the user previously typed. So if you exported say your "Jobs" calendar and typed "Jobs" as the destination filename, then "Jobs" will show up even when you later export say your "Routines" calendar. You probably want "Routines to pop up instead to save you from write over the existing file.

The default destination filename should be the name of the calendar.
