[PATCH] Sheep are affected by auras

[elexis]

When selecting a hero with an attack aura, all nearby sheep will show the aura icon, which seems counterintuitive, as sheep can't attack.

Reported by Hannibal Barca.

Yes they have the Unit class (son of template_unit) and many auras affects the Unit class. For most of the aura, adding Human class should fix that.

[sanderd17]

Simple: replace the Unit class requirement in the hero aura by "Soldier".

[fatherbushido]

Sanderd17 class suggestion is even simpler. (sometimes siege can perhaps be affected too) patch :

• use more consistent classes
• add iber monument aura description and name (from design docs)
• fix some typos (my bad :/)
