* 'master' of https://github.com/xDrapor/SafeGuard.git:
  Added restriction for player max Y position.
  Corrected NPEs associated with publishCheck(). If you do not immeditately return after a publishCheck() you must check for null before you continue.
  SGCheckFlight... the flight check to end all flight checks. Trust in Mude :D let me finish this baby up and you'll see the glory of SafeGuard. Please test the crap outta this.
  Corrected findClosestGroundToLocation() in SGBlockUtil. Adjusted brackets on conditional in SGCheckFlight.
  Corrected the NPEs getFalling()/getSafeDistanceY() were receiving from not having getSafeLocation() set on player first join. Instead of conditional(which was only for testing if the error was fixed) move to SGPlayer instance creation?
  Added isTracking() to SGPlayerManager (Improved readability). Added isPlayerOnline() to SGPlayerManager.
  Rollback of 'master' due to errors. You need the batch script I wrote to build 'mvn -P SNAPSHOT'. Regular building 'mvn package' or 'mvn -P RELEASE' are fine to use without change. xDrapors commits were readded.
