- Removed SCStart/EndBuffering as far as possible and fixed an issue with

the capture command in that it not put resluts into the Tcl interpreter.
  This broke scriptcontext scripts in complicated situations.
- Resolved some issues with the TAS calculation and negative scattering sense.
- Fixed a bug which did not reset the state to idle after checking
  reachability in confvirtualmot.c
