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.
It's not a performance benefit when creating the function, it speeds up when the function is called.  Every time you called element.method() ... calling .method() would be faster.
