V6 component overhaul.

[JSideris]

This task could be broken down further. These are misc thoughts on component usage that could be improved prior to the v6 launch.

• Remove non-component bindings Completely remove non-component binding. #155
• Event emitter pattern Refactor events to use emitter pattern. #146
• Better encapsulation for components Components should use the shadow dom for slotting and scoping.  #168
• Component vdoms should be more abstract rather than rendered elements. VDOM as data rather than rendered elements. #158
• Find a way to resolve the annoying binding problem. Right now, we need to instantiate components and assign them to a variable to bind them. There should be a more convenient way to do this (inline).
• Find a way to attach events and attributes to components inline Better way to pass data into components. #177
• Get rid of abstract component Component factory. #153
• Remove css parameter from style builder Refactor style builder. No more css parameter. #145
• There should be an easy way for a binding in a component to be synced with a child component. We seem to have gotten this for free with reactives.
