Webkit does not handle accumulate or additive attributes on animation elements correctly

This is visible in several of the test cases.  This example is one of the most noticeable however.

This is mostly the result of not having a working animVal/baseVal architecture, thus not being able to save off the original value.

Make multiple additive animations work.

I promise this is the last oversized animation patch, the rest will be easier to split up. :)

I made some comments in IRC about comments... in general it looks fine.  I assume you'll land a slightly modified version.
