yet another temporary strange but straightforward hack for a script at orange to work! that is: while Joseph is working on the actual Constraint API for bones etc., this allows our armature script to set influences with a simple call: armatureobject.setConstraintInfluenceForBone(bonename, constraintname, influence); fails silently at failure ('cause the c calls used do and no retvals are checked) and is in the strange place (as the current api is largely not object level) but works for us for now (e.g. next few weeks).
