Update 1.2 - Skeletons

I added a new family of enemies, skeletons.

The pack now has a regular skeleton and a skeleton king.

I've also changed the way the pack is arranjed. Now everything is separated into their own animations.

This should make it easier for anyone using the packs to get the proper animation sheet.

All packs were updated to this format so it's now easier than ever to find the sheet you need.

And that's hit for this update.
