Luanti 5.11 showed a lot of flaws in the shading of the CNC models, some
of which were previously obscured. Fix the models so that smooth shading
is applied where appropriate and sharp/flat shading where appropriate.
The modified files have also been run through ExeVirus' CompressObj.
This deprecates the variables onesize_products and twosize_products by using a shared definition table.
With these changes, it should be easier to add new programs in the future.
New feature: Tooltips are added to all programs. (only applies to newly placed nodes)
minetest.conf technic_cnc_use_technic = false disables
use of power, returns items instantly, uses only default
stuff in craft recipe
(defaults to enabled if technic is installed)
