Build: Advise to create test cases on JS Bin or CodePen, drop JSFiddle

JSFiddle doesn't support IE (even 11) anymore so we shouldn't advise users
to use it to create test cases. To make people have a choice, add CodePen
to the list.

Also, link to specific starter templates so that novices don't need to spend
time thinking how to set up the basic structure.

Closes gh-4289
