Cleaned up Camera to only split itself instead of all cameras in the scene.
Fixed offset bug so that camera position doesn't matter.
FarmTerrain and GroundTiles now spawn their objects at correct height.

Added offset to Y for both ground tiles and plants in order to prevent
clipping.
Water FX now play even when nothing is watered.
Renamed variables and added comments for clarity.
Cleaned up plant script. Reduced code, refactored a bit.

I took out a lot of complicated rendering behaviors that didn't
really need to exist. Also reworked the text to just be a letter
based on what the vegetable is. Added new materials for plants
to help tell them apart from the ground.
