new troop 'THE MOLE'

Dear supercell,

I had an idea that you maybe can add a new troop called 'the mole'
I think that it is pretty nice that there is a troop who can go underground when you drop him and go to the nearest defence tower. When the mole come above the ground he hit the defence tower for a couple of times. When the defence tower is wrecked he's going underground again. You can train him in dark barrack level 7.

the mole can't be upgraded
