Version 6

[minichma]

Now that we're about to release v5, its time to start discussions about v6, starting with those things that didn't make it into v5.

• Separation of Model and Operations (mostly as discussed in Version 5 #606 (comment)
• Use the Ical.Net types for representing the model but use NodaTime types for evaluation.
  I.e. the Ical.Net types have been designed for and are great in representing the ICAL model while NodaTime has been designed for and is great in doing time- and time-zone based calculations, dealing with related ambiguities, etc. The approach would be to have a clean translation layer between the Ical.Net types and NodaTime and then doing the actual calculations in NodaTime.
