Brian Birtles 2349318ce3 Bug 1046055 part 2 - Rename AnimationPlayer::IsCurrent to HasCurrentSource; r=dbaron
It's not the player that's "current" (a Web Animations term for an animation
that hasn't yet finished), but its source content, if any. This patch renames
the method on AnimationPlayer accordingly.

At the same time this patch moves the method to the header file since it's
quite simple and could possibly benefit from inlining.
