Enough fixes for the year (#568)

• Fixed Shockwave making a mess of lava (with water?)
• Fixed select range for leaves being extremely short
• Fixed EarthTunnel making a mess of sand. Sand will no longer fall when
blocks beneath it are mined out with EarthTunnel (if it reverts)
• Fixed SurgeWall (frozen) not returning water to bottles
• Fixed WaterSpout not breaking when toggling bending
• Fixed EarthBlast not selecting sand correctly
