the recorded data animations

On today's stream, I spent some time working on integrating a few animations into the recorded data to make the various scenes more interesting.

• I wrote a vertex shader for the grass to make them wiggle a bit.
• I integrated the Definitive Stylized Water asset and made one of them very wavy.
• I used a particle system to make it RAIN (I like rain)

Hopefully @Titanseek3r and I can finish this game soon!
