Add new functions related to underwater effects

[XJMLN]

Client functions

• setCameraUnderwaterEffectEnabled(bool state) - Enable or disable the underwater effect. This function does not affect the default diving behavior.
• setCameraUnderwaterEffectSpeed(float speed, float frequency) - Change the speed and frequency of the underwater effect
• setCameraUnderwaterDarkness(bool state, float maxDarknessDepth) - Enable or disable the screen getting darker as we dive deeper underwater. We can also set the depth at which the screen goes completely dark.
• getCameraUnderwaterEffect() -> bool enabled, float speed, float frequency
• getCameraUnderwaterDarkness() -> bool enabled, float maxDarknessDepth
• resetCameraUnderwaterEffect() - Reset the underwater effect state, speed and frequency to their default values
• resetCameraUnderwaterDarkness() - Reset the underwater darkness effect state and maximum darkness depth to their default values

Resolves #1297

Great! We can fix #2598 by checking if the underwater effect is on, maybe after this PR merged?

[XJMLN]

Currently, getCameraUnderwaterEffect will return true only if it was enabled by setCameraUnderwaterEffectEnabled. I don't know if this is valid; maybe I should additionally check the value of CWeather::UnderWaterness(0xC8132C), which is used to enable this effect and changing the weather to ID 20 while underwater. Then getCameraUnderwaterEffect would return true in that case.

I think we should be able to check the effect anytime without relying on setCameraUnderwaterEffectEnabled

resetCameraUnderwaterEffect() should not this also reset darkness too

and getCameraUnderwaterEffect() should not also get the darkness level too
instead of calling another function to check

Nice job!
Reset effects when a player connect to a new server. please

[Fernando-A-Rocha]

Good job, but please address the requested changed
