================
idPhysics_Base::SetWaterLevelf
Returns 1.0f if the object is in a liquid, 0.0f otherwise.
If the object's not in a liquid it double checks to make sure it's really not.
Normally we only set this->water when an object collides with a water material but
what happens if an object spawns inside a liquid or something? Nothing, it'll just sit
there. This function sets the water level for an object that's already inside the water.
This was most noticeable when I had monsters walking into the water and of course, they'd
sink to the bottom. After I'd kill them they'd die normally and not float. After adding
this function they float after they're killed.
