Couple of (hopefully minor) requests

[dsyee]

1) Is it possible to change the names of the Octane textures to be consistent with standalone (like "Octane Greyscale Image" instead of "Octane Float Image," "Octane Greyscale Color" instead of "Octane Float Texture," etc.)?

2) For Octane image nodes and SunSky, can the default "Power" be set to 1.0 instead of 0.9?
