A couple of route-logging thoughts

Just a couple of... requests? for future upgrades to the route-mapping feature:

* Could there be a way to add points into the middle of an existing route? Say there's an existing route, but a loop is added in the middle. Sure, that loop could be made into a separate route and then the mileage could be added manually on the log... But it'd be nice to be able to add points into the middle of an existing route.

* Similar to above... Could there be a way to edit an existing route by picking one of the points and say "delete everything after this"?
