[unity] Renamed Packages directory to Modules to prevent Unity from automatically loading the UPM packages contained therein. Otherwise it caused error messages due to nonexistend dependency checking and resolution.

 ### Unity
 
 * **Breaking changes**
+  * **Officially supported Unity versions are 2017.1-2019.1**.
   * **Spine `.asmdef` files are again active by default**. They have previously been deactivated to `.txt` extension which is now no longer necessary.
   * **Removed PoseSkeleton() and PoseWithAnimation()** extension methods to prevent issues where animations are not mixed out. Problem was that these methods did not set AnimationState, leaving incorrect state at e.g. attachments enabled at slots when starting subsequent animations. As a replacement you can use `AnimationState.ClearTrack(0);` followed by `var entry = AnimationState.SetAnimation(0, animation, loop); entry.TrackTime = time` to achieve similar behaviour.
   * **The `Shadow alpha cutoff` shader parameter is now respecting slot-color alpha** values at all Spine shaders. A fragment's texture color alpha is multiplied with slot-color alpha before the result is tested against the `Shadow alpha cutoff` threshold.

     * Nested classes `SpineEditorUtilities.AssetUtility` and `SpineEditorUtilities.EditorInstantiation` are now no longer nested. If you receive namespace related errors, replace any occurrance of

       * `SpineEditorUtilities.EditorInstantiation` with `EditorInstantiation`.
-  * **Timeline Support has been moved to a separate UPM Package** Previously the Spine Timeline integration was located in the `Modules/Timeline` directory and was deactivated by default, making it necessary to activate it via the Spine Preferences. Now the Timeline integration has been moved to an additional UPM package which can be found under `Packages/com.esotericsoftware.spine.timeline`.
