FlightTimer

There was an error with the EntityDamageEvent that would cause errors every-so-often that has now been fixed. There also was a memory leak that was being caused by me forgetting to add a return statement in the code and also a new feature has been added to the /fly command and allows for /fly <player> and now when /fly has been turned off you do not take fall damage.

Fall damage will now be negated for 30 seconds after flying stops so that if players are flying high and they fall they do not have to worry about dying and losing everything.
