Add overhead throw and lobbing for two handed objects

[SirPolaris]

Since we will have two handed objects, and we will have frisby actions for some smaller objects, and naturally throw and toss for grenades. Add the ability to throw crates, shells and other explosive ammo as desperation/impromptu weapons.

Only foreseeable problem is saboteurs using ammo stacks to blow up ammo stacks, without the need of satchels or other explosives. But, ammo protection is something we want to happen. As is, ammo stacks can be blown by grenade or incoming artillery. Forcing ammo stockpiles to be managed. So, it's not too far, to allow them to spike a shell.
