#13 Dates should sync multiple calendars

[Rick Ciervo]

iCal allows the user to have multiple calendars (Personal,
Business, Holidays, etc) but the Date sync plug-in only allows one
calendar to be synchronized with the Newt.

The most basic improvement would be to make nSync work kind of
like the Palm iSync conduit; all calendars can get sent to the Newt,
but any new entries entered on the Newt are always added to a
specific calendar (e.g. Personal).

Since the Newt Dates application can support multiple "folders", I
guess it would be possible to completely mirror the iCal multi-
calendar structure on the Newton.
