WorldBorder

IMPORTANT NOTE: This version is only intended for Bukkit builds for Minecraft 1.8+, specifically Spigot. It has been briefly tested on Spigot 1.8, 1.8.7, and 1.9 builds.

• Quick fix for minor bug in border knockback code that had it never consider a Y position of 1 as safe, even though it can be safe if the world is set up with only a single layer bedrock base at Y level 1.
• Added Bukkit Events which are fired when Fill and Trim finish, for use by other plugins to be notified of their completion. Specifically, the Events are com.wimbli.WorldBorder.Events.WorldBorderFillFinishedEvent and com.wimbli.WorldBorder.Events.WorldBorderTrimFinishedEvent. (by timafh)

Only tested on snapshot builds of Spigot 1.8, 1.8.7, and 1.9. Unknown whether it works with non-Spigot builds of CraftBukkit.
