Hack in projected walls
Points also just dumped to stdout. Some OpenSCAD changes still brewing.
Output projected walls/floor in the OpenSCAD script
Still needs cleanup and some walls/floor thickness logic tweaks
Typo fixes - assign to variable, not name
Changed wall_thickness to walls_enabled; more
wall and floor thicknesses no longer in cluded in scale calculations
floor thickness remains configurable in openscad (off if zero)
wall thickness no longer configurable in openscad (just en/dis-abled)
floor now situated below z=0, for simplicity figuring extrusion_height without adding floor thickness in (may change to translate other stuff upwards if enabled)
removed unused bounds definition in openscad
translate features up by floor_thickness rather than placing floor under z=0
