Load elements without imports

Added

• Ability to load elements without importing them (Thanks to @gazal-k)

New face, new name

Changed

• Renamed plastik-lazy-loader to plastik-lazy-route-selector to better
  describe what this element actually does. Unless some sort of freak
  accident occurs and pigs learn to fly, you can rely on this element's
  name staying as it is now.

Initial release

Routing just got easier!
