Auto-pilot shovel

Auto-pilot shovel is a weapon that can replace usual shovel that usually spawns at snowdrift in Winter biome. You can easily take it, but there is only 0.1% chance that it is auto-pilot.

Behaviour
The auto-pilot shovel will aim at the nearest player within 20 meters. If there aren't anyone, the shovel will just attack like a standard melee weapon. The shovel won't aim at someone who is disguised or invisible. The only way to dodge this shovel is being faster than it. It won't run after you, just fall down.

Known Bugs
Auto-pilot shovel can be turned into usual one for 5 minutes using Power Off ability. Maybe this is a feature and then it means that there is some mechanism inside it.
