Breaking bush block will not drop berries

[matejdro]

This is not really a bug, rather missing feature or maybe oversight.

Harvesting is bound to left click event rather than block breaking event which means only players can perform it. That lefts out all automatiion machines (for example ComputerCraft Turtle) since they just perform block break event without left clicking.

So request: if bush still has berries at breaking stage, drop both berries and bush.
