glue_bones fix: glue pass must act after "special bones" bones are put on forbidden layers (last 4) otherwise they get misinterpreted as ctrls. generate.py though, assigns use_deform to DEFs before layering and puts DEF on their layer after ORGs. So glue_bone must do cns after layering is done, AND generate its DEF _with_ layering and use_deform
