This should make it easier to distinguish between a few different widget instances with different destinations.

iSepta's caching headers could help this, but the app can also do it. Let's make the app do it too, just for fun.

The new iframe on isepta.org, while cool, makes it a lot harder to copy/paste a URL into the widget.

Ultimately it'd be nice to have the widget do train selection too, but I'll need a bit more thought time before I have something suitable for that.

This would turn the widget into a countdown of sorts.

For example bring up http://isepta.org/rr/start/8/end/111/now/trains/6638/stops

I'm thinking the link should be underline only on hover. Underline on all of them might look too busy.
