Add Mass and Aura spells

Many spells work fine as mass spells inspired by Mass Teleportation. However, they can get pretty unfair and need balancing or to be ultis. We are not sure how to make them work with AI if they are based on channel with a target area. They will probably need some custom code to order AI to cast them.

Place the dummies with missiles at the caster's position, increase their spell range to 999999, so we can see a missile flying from the caster.
