V1.15.0

• Add Player Toggle (/vs toggle), This will toggle whether the player is teleported or not when entering the void. 
• New Permission "vs.player.toggle"
• Altered "/vs set" behaviour so that the world mode is also set spawn.

Thanks to ShadowDragon7015 for his contributions.

V1.14.0

• Add uSkyBlock Support
• Fixes bugs involving shared islands for IslandWorld and aSkyBlock

V1.13.0

• Removed vs.override permission: Was causing more problems than it was worth.
• Add keep inventory flag (/vs keepinventory (true/false) [world]): If set to false, the players inventory is wiped. Defaults to true if not set.
• Add hybrid mode (/vs hybrid (true/false) [world]): If set to true. Will run both the command mode as well as the other mode. Command mode is ran after the other mode.
• Offset now works above the void. A negative offset is above the void and positive offset is below the void.
