Animate time along with flights

This is a little bit of UI design that might make @emackey proud of me.  I noticed that we were jumping instantly in time whenever someone selected a new image to fly to.  I've updated the code create an animation that moves to that time in the same duration that it takes to fly there.  Depending on where you are and where you are going, this actually creates a really nice effect (in my opinion).  Try this:

1. Start app
2. Click on 4th row of grid.
3. Click on 5th row of grid.
4. It makes it look like the ISS is speeding along to go take your picture for you.

We can tweak this if anyone has further ideas, or if people don't like it, we can just close the request.
