Improve trip transfer experience - filter older arrivals when user views stop coming from another line

[barbeau]

Summary:

Described more in detail here for iOS:
OneBusAway/onebusaway-ios#452

Here's the scenario:

1. I am catching a 10 bus at 15th and Republican and it arrives in 4 minutes
2. I am going to take it to Pine and 9th, where I will transfer to a 218 to Issaquah

The stop UI that is presented after I tap on "Pine and 9th" should hide all of the vehicles that depart before my scheduled arrival time, presenting some sort of option to display them to the user if desired.

See further discussion on the iOS issue for an improved solution.

Steps to reproduce:

1. Tap on a stop in trip status view

Expected behavior:

By default hide all older irrelevant arrivals that would happen before I arrive at that stop (assuming I'm transferring to that line)

Observed behavior:

All arrivals are shown
