Discrete Command "Use" leaves the inventory as is

[geekstor]

The Continuous Command "Use" depletes the used object from the inventory gradually. "Use" works in discrete mode now as well 😄. However, using the Discrete "Use" command does not change the inventory. Suggestion: Reducing the number of the used object from the Inventory by 1 on each "Use" command for the Discrete version.

Pending merge of #287:
"use" should now deplete the inventory, and "attack" should now add the block drops to the inventory if a block is destroyed.
Have also implemented normal Minecraft logic to prevent blocks being placed in a square that is currently occupied by an entity. (Stops the agent suffocating themselves by building a block around their own head...)
