[unity] Renamed misleading `MixMode.SpineStyle` enum name at SkeletonMecanim to `MixMode.Hard`. SkeletonMecanim `Layer Mix Mode` now defaults to `MixMode.MixNext` instead of `MixMode.Hard` for new instances. Closes #1505.

       The Project panel should now show an entry `Spine Timeline Extensions` under `Packages`. If the directory is not yet listed, you will need to close and re-open Unity to have it display the directory and its contents.
+  * `SkeletonMecanim`'s `Layer Mix Mode` enum name `MixMode.SpineStyle` has been renamed to `MixMode.Hard`. This is most likely not set via code and thus unlikely to be a problem. Serialized scenes and prefabs are unaffected.
 
 * **Additions**
   * **Spine Preferences stored in Assets/Editor/SpineSettings.asset** Now Spine uses the new `SettingsProvider` API, storing settings in a SpineSettings.asset file which can be shared with team members. Your old preferences are automatically migrated to the new system.
