Find and replace sprite renderer color editor utility

This release features the find and replace sprite renderer color editor utility for Unity 3D.

• Select a color using the color picker tool in the editor
• Choose a replacement color
• Choose a variance (colors can sometimes vary very slightly based on what was picked) - so use a low variance like 0.01 to ensure that similar colors are not replaced too.
• Hit replace to replace all sprite colors in the scene that match the picked color within variance range with the chosen color
