shpindex depth

As Mapnik's shapeindex utility does not have optimized defaults, I matched the Mapserver depths used exactly (Shptree notes):

I found that deeper trees did not have much benefit so (instead of what is listed below) I simply used the default depth of 8 (which is what is used if no options are specified)
