Switches a number of places in Resource::Logic to use abstract_clock::now()
which returns a time_point. Unfortunately Resource::Logic tracks time
locally also, but with ints, not time_point. So Resource::Logic uses a
delicate mix of abstract_clock::now() and abstract_clock::elapsed() with
this commit. That inconsistency could be addressed in a second commit.
