added a block for jullus

Jullus now has a block. Unlike Jonar, Jullus's block does not do any damage and only acts as a way to dodge enemy attacks. It's also much easier to time.

To make this block make more sense to use, I'm planning on changing how Jullus's block works so that you can charge up an attack, walk a little bit, then unleash it. If the player realizes that they didn't quite time there charge attack they can dodge last minute and then unleash the charge attack. It would also be cool if you could gain energy every time you dodge an attack as Jullus.

Any thoughts?
