Space meteor showers visualization powered by SpaceKit.js

Remember to try "Everything at once" in the top left dropdown menu!

Feature requests:

* Add an option to paint each shower with a different color.

* Add an option to show the planets (big enough to be seen).

* Add an option to zoom (in desktop, with mousepad) (perhaps it's possible but I missed it)

Even more feature requests/questions:

* Add an option to show Pluto and friends, in case it's relevant. Is it relevant?

* Add an option to show Ceres and friends, in case it's relevant. Is it relevant?
