Spreadsheet: Display geometry volume component grids

This shows a geometry's volume grids in the spreadsheet.
Three columns are displayed:
 - Name: The text name of each grid
 - Data type: Float, Vector, etc.
 - Class: Fog volume, Level Set, or unkown

In the future, values of the voxels themselves could be displayed,
but that is a much more complex problem, with important performance
implications, etc.
