Subject: [PATCH] Clean up examples directory

This CL removes a bunch of examples that don't actually work in the current
engine. I've also renamed example-element to custom-element and
example-scrollable to scrolling because the word "example" in the name is
redundant with the name of the directory.

-Others are examples of what sky hopes to one day support.
