Timber!

Makes it so trees fall down when cut.
!Demonstration

A "tree" is defined internally as:

• 2..512  logs of any kind
• 1..1024 non-permanent leaves of any kind

Logs connect diagonally and are initially checked upwards from the first log that is broken.
Trees will not fall down if:

• the player is sneaking
• the item used to cut down the tree has silk touch
