Update WorldGuard for CommandBook 3

[DarkArc]

This must not be merged until the CommandBook builds are fixed, otherwise, we'll break the WorldGuard build.

[wizjany]

note: figure out what to do with

WorldGuard/worldguard-bukkit/src/main/java/com/sk89q/worldguard/bukkit/BukkitConfigurationManager.java

Line 112 in c413cf4

Class.forName("com.sk89q.commandbook.GodComponent");

and probably update

WorldGuard/worldguard-core/src/main/java/com/sk89q/worldguard/session/handler/GodMode.java

Line 45 in 6c5319f
