Push animation value 'inherit' handling into SVGAnimateElement

Push animation value 'inherit' handling into SVGAnimateElement

Handling of 'inherit' doesn't need to live on SVGAnimationElement,
because only SVGAnimateElement makes use of it. Move it down the
class structure and simplify.

Also refill/wrap comments in the files touched to 80 columns.
