Bug 1004383 part 1 - Put StyleAnimation on the heap; r=dbaron 

This patch takes StyleAnimation and makes it ref-counted heap object. This
should allow us to store StyleAnimation and its subclasses (transitions only
currently) in a consistent fashion (an array of base-class pointers).
Furthermore, this will be helpful if we want these things to be pointed to
from Javascript objects that may, for example, preserve their lifetime beyond
that of the element that currently owns them.

This patch also introduces a typedef for an array of refptrs to StyleAnimation
objects (and similarly for the subclass ElementPropertyTransition) to simplify
the code somewhat.
