Stealthy Recon and Monks

Removed erroneous Ranged tag from Ranger and Inca's Warak'aq.

1. Recon and Monks get +7 defending vs ranged attacks
2. Highlander ignores terrain movement penalty.
3. Sun Wukong also gets stealth.
4. Corrected Oligarchy text.

Lowered Spec Ops' melee strength to fix the bug. Melee and Ranged strength should not be equal because it will mess up the combat preview.

Restored Spec Ops' range 2 but they have a -10 CS penalty when firing non-adjacent targets.
