fix issues

- disable bmx import/export temporaryly
- optimize the ui display of importing/exporting. (use box to organize props)
- place button horizontally, not vertically in virtools material.
- disallow apply in legacy align if no axis selected.
- add applied step counter in legacy alignment.
- add feedback for reseting bme material/component. (add a message box to show success)
