Updated the json files for the goblin assets. They are using "default" now for their skins. Also added an option to the SpineToy toolbox.

1. Click on Show Tools (bottom right corner)
2. Pick an asset from the middle list that is shown. Currently has SpineToy:TestSkeletonAsset, SpineToy:GoblinBoy, SpineToy:GoblinGirl.

Selecting one of those will reset the toy and assign the new asset.
