Add Foam to Waters edges and Water refactoring

[JamesTKhan]

Adds a basic water foam effect to water edges. This may be expanded on in the future but should work well if/when some kind of wave/mesh deformation is implemented.

Foam effect adapted from http://fire-face.com/personal/water/. Since we do not currently have wave deformations the foam scrolls by offset UVs instead. This means the foam only scrolls in one direction currently but hoping to improve on this later.

• Add softer edges and water foam effect to water intersections with other objects like shorelines.
• Add 5 customizable properties for foam effec
• Add new Depth Shader to support foam and soft water edges. Depth Shader was used instead of Depth Texture Attachments to try and be GLES 2.0 compatible
• Modify behavior of asset loading on project load. Added a check on project load that makes sure standard assets are present. If they are not present, then they are loaded/created and assets have to be reloaded after that. This supports backwards compatibility.
• Refactor duplicate code in the water shader and water widget.
• Render wireframe when water objects is selected (I missed this in initial water PR)
• When I developed the water feature initially I stored water settings in a MetaWater object. I have since learned that they should instead be stored in the Asset file not the Meta file. I migrated all water properties to the asset file. It should be backwards compatible but all existing water settings will be reset to default.
• Add a WARN LogType that displays warning Log Messages in Orange color.
• Fix issue with Shine Damper attribute not saving and loading properly
