[as3] Ported VertexAttachment id and Timeline/Animation#apply changes

CHANGELOG.md

@@ -16,6 +16,7 @@
   * Added `PointAttachment`, additional method `newPointAttachment` in `AttachmentLoader` interface.
   * Added `ClippingAttachment`, additional method `newClippingAttachment` in `AttachmentLoader` interface.
   * `AnimationState#apply` returns boolean indicating if any timeline was applied or not.
+  * `Animation#apply` and `Timeline#apply`` now take enums `MixPose` and `MixDirection` instead of booleans
 
 ### Starling
  * Fixed renderer to work with 3.6 changes.
