Clarify arrival/departure listings at the beginning stops of routes

[aaronbrethorst]

Expected behavior

When looking at a stop that is the layover/first stop for a route, I should be able to tell at a glance when a particular vehicle is departing the stop.

Actual behavior

I have to very carefully parse the text that is displayed for that stop to understand what is an arrival vs. a departure.

Steps to reproduce the behavior

1. Select the Puget Sound region.
2. Open Stop ID 13200

Yes, this is a primary comment we get about the OBA apps - knowing the difference between arriving and departing buses at terminals.
