fixed trips from the stop viewer (right click on stop)
TODO: not much use if the stop time is blank, or worse there is no
headsign. Which is the case for most of Mumbai.
We can perhaps fix the latter by demanding the headsign is set to the
last stop if not provided otherwise. Determining the aproximate arrival
time of an untimed stop is more problematic. The inly relaible thing to
do is show the last timed stop.
Both these wil need either whoping great sub querries, or some tedious
and expensive iteration client or server side of the results.
