Pushing zombies over low fences

[MrTrololo]

we should be able to make push zombies over low fences and make them flip on the other side of it, would be useful in combat and would be funny as well :)

I'd really want to have this, when you think about it it's not something you'd scream for, but they way this was handled is kinda sad. When you shove a zombie into the fence over and over, there's a chance that zombie will decide on their own to climb over the fence away from you, they the'll get up and come climbing over the fence towards you again which is a good what!? moment. This feature would fill up this sad "bump in the road" with a unique animation for pushing a zombie over the small fence with a modest chance of it happeni after 2-5 shoves to avoid just tumbling over a whole horde with a single shove.
