Add all scene variable attributes to the render log

[jlanz]

All SceneVariables attributes should be listed near the top of the log.

• Values that are not the default can be noted with an asterisk
• Attributes should be sorted alphabetically

For example:

SceneVariables("__SceneVariables__") {

The above example of what it could look like is copy/pasted from the output of running rdl2_print -c SceneVariables, although I added the '*' next to the "pixel_samples" attribute to highlight the fact that '8' is not the default value.
