Merged WaterWave into WaterSpout, OctopusForm Config Option

Merged WaterWave into WaterSpout:
    - WaterWave is no longer an individual ability.
    - WaterSpout has been split up into two different functionalities:
        Spout: Left click a non waterbendable block while over water.
        Wave: Left click a waterbendable block to select it as a source. Hold sneak for two seconds and then release sneak to launch off, creating a wave of water at your feet. You can press shift to cause the wave to disappear.
    - Added the previous WaterWave config options to WaterSpout.Wave
    - Added a permission to disable the WaterSpout Wave, "bending.abilities.WaterSpout.Wave"
    - The "bending.abilities.WaterSpout.Wave" permission is enabled by default.
    - Modified the WaterSpout description to reflect the new changes.
    
OctopusForm Addition:
    - Added a configuration option for OctopusForm called FormDelay which determines the speed of OctopusForm.
