Capture the Sheep mode

[Josef Kufner]

A new game mode, where players capture enemy sheeps.

• The Sheep is a dumb sheep which can be controlled by any nearby unit just like ordinary sheep (they will change color).
• Sheep has "heroic" (star) cursor.
• Sheep is immortal. (And villagers will not eat them.)
• Other player must capture all Sheeps and bring them to their territory.
• Sheeps cannot be garrisoned (but you can build a wall around them).
• Sheep can be transported by boat. If boat is destroyed, sheep respawns at nearest home territory or CC. Or we can let Sheep swim.
