Turbulence respects viewport and projection offset
Default value for WaterFogData plane distance

Set the default WaterFogData plane distance to be the same as global
bounds.  This solves an issue with the connection's control object
mistakenly thinking it is under a water plane in a debug build.

Default value for WaterFogData plane distance
Underwater Fixes

- Caustics now respects the passed in water plane rather than assume
that the water plane is on the XY plane.  This allows for caustics to
work for steep rivers.
- Fixed lerp() warning in underwaterFogP.hlsl.
- Cleaned up turbulence and caustics PostEffect scripts to remove unused
items.
- Caustics are now enabled and disabled based on the control object
being underwater, just like turbulence.  Moved this code to fog.cs to be
with the underwater postFX.

Update pxMultiActor.cpp (fixed)
Revert Player Buoyancy Change

This reverts the change made by
https://github.com/GarageGames/Torque3D/pull/490  It actually goes
further and comments out the Player's buoyancy calculation rather than
just the change in velocity.
