transitPlan: Add method to insert new itineraries
Adds a method to add new itineraris, either setting
a fresh set, or extending the previous. Sorted either
on departure time ascending, or arrival time descending.
This was previously done in the OpenTripPlanner plugin,
but moved to avoid code duplication in new plugins.
