Fixes #881 - Export component prototype methods on the HTMLElement

Here's a first pass. I kinda like the way this API feels -- it's important here that we're pretending the `can.Component` prototype is the `HTMLElement` prototype (with a couple of exceptions for other options).

See the test case for other/various little details about how this works.
Benchmarked on Chrome: no noticeable difference.

I get 480-510ms from calling the current version 100k times, and 480-505ms from calling the new Function version the same way.
