SimplePlayerWarps

Added

• The /warpedit command.
• Private warps. A warp can be made private using /warpedit, and setting the private property to true.

Changed

• /warpinfo now shows the UUID of the author if a display name isn't saved.
• /warpinfo, /warpdel, & /warp's messages were made to be clearer.

Fixed

• Crash when a warps author is null.
