News: SardanaAIO3 -t; nxselector docu, MotorLogger and ZMX

• SardanaAIO3.py: request from P09. Re-use tags that have been selected before.

   
  SardanaAIO3.py -x -t default
    use the tags stored in AIO_INFO
  SardanaAIO3.py -x -t display
    display the tags stored in AIO_INFO
  

  This change made it necessary to distribute a new version of hasyutils.

• nxselector docu: see here

• MotorLogger3.py saves also ZMX attributes for Oms motors that have the ZMXDevice property (in /online_dir/MotorLogs).

  Reminder: if the property ZMXDevice is defined and FlagCheckZMXActivated == 1: before each move (also vvc) it is asserted that the Deactivation ZMX attribute is 0.
