DD Release: 6.1.022

Changelog to version 6.1.021:
- now with SP deviation histogram e long data and graph in menu for AMS Export
- cmd 157/111 added (6 extended status)
- fixed labels of 2 histogram graphs

Remarks for AMS enhanced DD for SAMSON positioner type 373x-3 device revision 6:

DD limitations:

- this AMS installation does not contain the following parameter/graphs:
-- graph for data logger
-- graph for static characteristic
-- graph for FST (Full Stroke Test)
-- PST-Graph: complete, only e curve not displayed

- the data for the histogram curves were read automatically, but AMS and Field Communicator do not redraw 
the curves immediately. Same with the graphs which were read via read button (i.e. step response).
These graph windows must be closed and reopened to show the new curves.

- many text strings were shortened due to Tokenizer limitations
