Previously the logic manager was used as a global variable for SCA_ILogicBrick::m_sCurrentLogicManager, this request to always update it before run any python script and allow call function like ConvertPythonTo[GameObject/Mesh]. The bug showed in T48071 is that as exepted the global m_sCurrentLogicManager is not updated with the proper scene logic manager. Instead of trying to fix it by updating the logic manager everywhere and wait next bug report to add a similar line. The following patch propose a different way: - Every logic brick now contain its logic manager to SCA_ILogicBrick::m_logicManager, this value is set and get by SCA_ILogicBrick::[Set/Get]LogicManager, It's initialized from blender conversion and scene merging. - Function ConvertPythonTo[GameObject/mesh] now take as first argument the logic manager to find name coresponding object or mesh. Only ConvertPythonToCamera doesn't do that because it uses the KX_Scene::FindCamera function. Reviewers: moguri Differential Revision: https://developer.blender.org/D1913
