Sentinel (new trap defense)

What's this?
A new defensive structure which can only be placed on walls.

When will this available?
When you hit TH11

How does this function?

1. Whenever a troop comes nearby within range, trap is activated and the wall become a defensive structure.
2. It is destroyed when the wall is destroyed. Earthquake works wonders.
3. It is targetted as a wall which means wallbreakers deal bonus damage against it and will prefer targetting the wall piece where it is placed instead of other walls.
4. Any other unit will ignore sentinel but if they have to break through a wall the wall piece where it is placed will be prioritized.

What happens when trap is activated?

1. It is activated as a low DPS ground/air turret (because walls have up to 7k HP it is very OP otherwise)
2. It slows nearby units
3. It is activated as a DPS with 1/10 of the wall's HP. If the defense is destroyed the wall piece remains intact.
4. It deals large damage to the unit triggering it
5. It turns into very cool robot like unit and function as CC defense
6. Anything of the above or Supercell decide
