AirCombo Changes, NPE Fix, LavaFlow config change

Decreased the Twister Particles:
    - Reduced the total amount of Air particles created by Twister to reduce lag.
    
Made AirSweep less glitchy:
    - AirSweep now reacts better to the players sweeping motion. Previously AirSwipe would glitch out if the server was having TPS lag.
    
Changed the LavaFlow default Left Click values:
    - Previously LavaFlow started cleaning up the lava 5 seconds after the player left clicked, this proved to be too fast since LavaBenders were unable to launch LavaSurge within the time frame.
    - LavaFlow now starts to clean up after 7 seconds instead of 5 by default.
    
AirCombo less likely to kick players:
    - Players were being kicked from the server for flying while being affected by Twister and AirSweep, this should happen less often now.
    
Fixed a NullPointerException caused by checking for AirSwipe collisions
