Retire the Unity mine: Mine, MineManager, the Mine Launcher prefab and ShieldManager's mine branch

Operator ruling mines-back-in-sim-asap: delete now, return as a simulation body.
Mesh, materials and BigExplosion stay for the sim-mines presenter. GridObject
stays for the pickups until loot-1 r2. Comments in FireControl.Detonate and
HullCollider drop the deleted callers. Builds not yet verified at this commit.
