Skin JSON files can now use the simple names of classes

[ProZhar]

Hi. With using 1.9.9-SNAPSHOT version I've got an error with new features of skins's simple names
Can you add support fo this new features?

• Skin JSON files can now use the simple names of classes, i.e. "BitmapFont" rather than "com.badlogic.gdx.graphics.g2d.BitmapFont". Custom classes can be added by overriding Skin.getJsonLoader() and calling json.setClassTag().
• Skin supports cascading styles in JSON. Use the "parent" property to tag another style by name to use its values as defaults. See https://github.com/libgdx/libgdx/blob/master/tests/gdx-tests-android/assets/data/uiskin.json for example.

Done. Simple names and the parent property should work correctly now.
