Previously, the two versions of this sample app had separate copies of the
stock data. This CL moves the common data to the common data directory so that
they can share. Also, I've switched the data files to be |dart| files rather
than |sky| files to make them easier to use from fn examples.

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.
