- Removed old stuff in conman

- Fixed a bug in processnode which hangs SICS when processnode is called from multiple
  clients on the same node
- Fixed a bug in multicountsersec which caused thrashing of the Tcl results which caused ugly
  error messages when calling the transfer script. Now a copy of the connection is made
  before calling the transfer script
