Materials: Editor UI enhancements

When creating a new material, assigning the basic
rendering model to the material resulted in an all
black color. This will now be assigned the default
color as specified in the preferences.

The name of the material Properties tab has been
changed to Physical for improved consistency in
the user interface.
