Surveyor Map Framework

Changes:

• fix waypoints not being server-wide when set to SERVER
• fix xaero's migration not being triggered in multiplayer
• default globalSharing to true (for new installs)
  • discovery of surveyor's primary feature (server-wide mapping) is surprisingly low
  • readme has been updated to reflect this and advise public servers to disable global sharing
