- Added triple axis scan command.

- Introduced simulation mode to simdriv and simcter, i.e they never fail and
  finish at once.
- Started defining MAD compatibility commands in Tcl
- Fixed a bug in FOCUS_src which caused it to leak sockets.
- Introduced setsockopt SO_REUSEADDR to all new sockets in sinqhm in order
  to loose the next sinqhm error.
