technic_cnc: use programs definition to generate formspec (#647)
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)

-- Technic CNC v1.0 by kpoppel
-- Based on the NonCubic Blocks MOD v1.4 by yves_de_beck
-- Idea:
-- Somehow have a tabbed/paged panel if the number of shapes should expand
-- beyond what is available in the panel today.
-- I could imagine some form of API allowing modders to come with their own node
-- box definitions and easily stuff it in the this machine for production.
