Title: [B+C] Add a hurtEntities setter to FallingBlock. Adds BUKKIT-4752

##### The Issue:
There is no current way to set FallingBlock's hurtEntities field without accessing NMS.

##### Justification for this PR:
With this addition plugins will be able to set hurtEntities through Bukkit API.

##### PR Breakdown:
This PR adds a new method setHurtEntities to the FallingBlock interface in Bukkit, and implements that method in CraftFallingSand in CraftBukkit. Additionally it makes hurtEntities field public instead of private in EntityFallingSand.

##### Testing Results and Materials:
Test plugin code: https://gist.github.com/YaLTeR/6509037
Test plugin JAR: http://www.mediafire.com/?22hphez9qw2a423

Test plugin commands:
/hetester nohurt - spawns an anvil ontop of you that does not hurt you.
/hetester hurt - spawns an anvil ontop of you that does hurt you (made using the API method from this PR).
