The Atlantis Mod

The Atlantis Mod adds the aquamite armors and tools, as well as a portal to the atlantis dimension.  The mod is a work in progress, and its my first mod, so i appreciate any feedback you might have.

Bugs:

Every few seconds, a zombie pigman will spawn at the portal.

To make a portal, Make a portal frame out of Aqua Stone, and use a portal ball on it.

Tools and armor are the normal recipes, but with Aquamite.
