Improvements to journey info table

[hathix]

I was viewing this route comparison:

Thoughts:

• Isn't it a bad thing for on-time rate to go down 20%? In that case, shouldn't the text be orange/red instead of green?
• The completed trips metric isn't all that useful, since the date ranges are different lengths. "Completed trips per day" for multiple-day routes would be ideal.
• For Median Wait Time, I'd rather see it called "even" rather than not having a label at all.

I'm starting to work on this in the route-table branch. Others can run with this if I don't finish it quickly.

Update -- no need for "even" since nothing is truly equal. In my branch I'm just going to make it show "<1" if the difference is very small; currently that code path doesn't trigger.

But I did fix the on-time rate coloring issue. The completed trips metric might be big enough to deserve its own PR.

The completed trips bit is hard. You'd have to do it per hour for it to really be valuable.
