Manually created shaders causes the Inspector extension to throw a warning

Here's a good one:

Once ShaderForge is installed, selecting manually created shaders causes the ShaderForge Inspector extension to try and compile that shader, then throw a warning. Considering that it has a button linking to "Replace with Shader Forge shader" -- this seems dangerous -- maybe there could be a change to the interface.

• Rather than a warning, the inspector notes that the shader is "not a ShaderForge shader".
• The inspector then presents an option to open ShaderForge and replace it - with a popup warning about the destructive editing the user is about to do.
• Maybe stay away from the iconography of warnings for shaders which aren't built in ShaderForge -- reserve it for misconstructed ShaderForge shaders.
