Styling tweaks

[akre54]

This pull doesn't introduce any logic changes, but it tweaks some internals, notably with this context and === instead of ==, some underscore method tweaks, and keeping the selector as ":el". Mostly trying to keep == from biting with edge cases.

Beautiful. Thank you.

I like the removal of self = this when not needed, as in some of this diff. Unfortunately, the change introduced a this inaccuracy in the call to updateViewBindEl() inside the event-handler, where the event's context has this as, e.g., HTMLInputElement instead of a view instance. Pull req pending.

I only see one other potential case of this. Both lines flagged as notes in the commit itself.
