Remove commented out code.
When we have an airport display it to start.

This will now start in the airport view whenever possible. When it is not we
instead display the circular view.
Add a well for related structures.

This well shows all related structures and provides links to their 2D diagrams.
This is a useful thing Anton has requested and this is a basic version of it.
There are some problems with it. Notably the size of the jmol window above and
it do not match up. In addition I think the 2D diagram is now stretched so I'll
have to fix that.
Align jmol and related structures.

We align the related structures block and the jmol div because it looks better.
Also, I've changed the title of related structures to say that is 2D we are
linked to. I also fix the styling so links are not bold in the block.
Remove unneeded <p> element.
Prevent jmol div from being hidden.

No need to hide as we always display it. In addition we remove the showing code
since we always want it present.
Make interaction buttons toggle.

We want the interaction buttons to toggle states. To do this we add
data-toggle=button to each button.
