New update v1.11 now available

Another update with a pretty cool new feature:

* New Feature: You can now export seamless animations, so that they can be used as animated textures tiled seamlessly side by side.
* New Feature: Remove unused shapes by right clicking on the shapes list and selecting “Clear Unused Shapes”
* The context menu on the shape tab will now work by clicking anywhere in the list area (previously it only popped up by clicking on an icon)
* Fixed a bug causing the playback of an animation not to work properly after exporting an animation
