More app tweaks

Today I addressed a handful of tiny inconveniences in my app, mostly surrounding the route trip listings. Those listings now require less jumping around when trying to learn about a route that isn't currently running. I also adjusted some of the "landmark" stops used in the new trip summary feature. Once the bus company releases the full data set in August I will probably need to add a few more landmarks to display the (numerous and arcane) school district diversions in a helpful way.
