New animation sound conditions

[Sezzary]

Revises animation sound effect conditions. Will require asset updates for water creatures later, but for now their sounds are handled with a special exception.

Old sound conditions:

• Always
• Land
• Water

New sound conditions:

• Always
• DryLand
• WetLand
• Swamp
• Underwater

To test:

• Underwater sounds should only play when the camera is submerged.
• Swamp sounds shoudl play only in swamps.
• WetLand sounds should play in shallow water as before. Check on sloped surfaces.

I propose to leave Land as Land, and rename WetLand to ShallowWater.

I've tried to test it but I'm getting compiling errors.

In Jeep there is DryLand, so now it should be "Land"?

In animation.cpp line case AnimCommandType::Flipeffect:, the compiler says the initialization of frameNumber is omitted in this case. Maybe a version conflict affected this PR somehow?
