Remove skate.when support. Add attribute helpers. Reorganise code. Move template renderer into template namespaced functions.
Remove attribute helpers for now.
Add ability to specify default content for <content> elements.
JSDoc allthethings. Refactor default HTMl templating to use a data-skate-content attribute rather than <content> tags and the 'select' attribute for less invasive templating and simplicity. Add ability to use the 'is' attribute for binding tag components to existing elements.
