Rolling logs and other cylindrical objects (barrels, wheels)

[MarmaladeToast2 4]

We should be able to roll large and heavy cylindrical objects, as these are coincidentally the ones players encounter most frequently.

Rolling logs would be extremely useful for building when trees are far away. Gravity should make logs roll fast downhill, requiring a bit of planning ahead. When logs reach higher speeds, the player will have less control over it, requiring some planning ahead. This will be convenient when building, as carrying logs is slow and makes the survivor vulnerable.

Barrels and wheels should be rollable as otherwise the only option is to have one spawn close to where they are required (as wheels cannot be carried in backpacks anymore and barrels are somewhat rare).

Rolling objects should be affected by gravity, and accelerate when rolling downhill. As objects roll faster, they are harder to control and steer, and the player may eventually lose control of the rolling object. If such an object is going fast enough, it should cause serious damage to anything it hits (or even itself, should it collide with a hard obstacle). This would make for some funny ambushes or fails. A rolling log that hits a survivor's legs might cause them to fracture. The log should not kill the player rolling it (wink wink... car physics), as long as that player is behind the log with respect to the direction of travel.
