Final Fantasy IV/Nintendo DS changes

The main change from the first release of Final Fantasy IV is the difference in spell and ability names. For example, "Fire2" has been renamed to "Fira" (in other words modern spell names). Additional changes:
 * A new Augment system has been introduced for more flexible gameplay.
 * The Twincast ability that Palom and Porom have has been changed with the addition of extra spells that can be used with the Augment system.

NOTE:Some of these changes were first introduced in Final Fantasy IV Advance for the GBA.
