This allows to add or remove items to/from groups using lua. The sample mod implements a simple "blacklist" feature that only blacklists spawns, not recipes.

Extended wrapper generator with the ability to have a different cpp_name and lua name for attributes.
Added/changed several itype wrappers.

I changed a few attributes from their previous names to make them have the same name as in the JSON. Modders are more likely to be familiar with JSON than with C++.
line_to won't crash now when drawing from/to same spot (#6900).
Forgot the return.
