WORLDGUARD-2636 - Reported by Antonie

Dear Developers,

When I place a wither BEHIND a region, and the region is flagged: other-explosions deny, the wither will explode and damage the region, I hope that you guys could add or repair that. And maybe you guys could make a new flag: Falling-damage deny, so when a player falls on the ground in the selected region, that he won't get damaged. Also when I make a region and flag it: lava-flow deny and I place lava behind the region, the lava will flow into the region.

Thank you Antonie
