Build the facilities to add a new time/distance workout

This adds the code to show the new records in the UI, plus it adds them to the view model. Some of the representation changed in order to facilitate linking UI elements to particular records. There are now some buttons to create workouts of various types, clicking on a button adds a new row to the UI, and it also adds a new record to the view model. Saving the view model writes the records to the database.
