- PyLineSpit() - used to print the filename and line number for internal errors now works when executing class functions in a module.

- replaced PySys_GetObject("modules") with PyImport_GetModuleDict()
- use defaults for keymap import/export rather then setting the same value every time from the UI scripts.
