py_ext: fix CSV Writer

fix POU logic :
- SAVE is a BOOL
- invocation of py_eval on rising edge of SAVE
- remove save python argument

fix python:
- use no encoding for file open (python2)
- re-use detected dialect if any
- use no "rt+" and truncate since no need to re-sniff dialect for output file
- return "OK" instead of "#SUCCESS", preventing POU logic to ACK result
- support creating new line if writing just after last line
- support appending data on short rows

fix example:
- use a HMI:Button to trigger CSV write instead of HMI:Input +1
- reload CSVs on on each new CSV opened in file browser
- add display of CSV write output

    TextList widget is a svg:group, list items are labeled elements
    in that group.

    To use a TextList, clone (svg:use) one of the items inside the widget 
    that expects a TextList.

    In this list, (translated) text content is what matters. Nevertheless
    text style of the cloned item will be applied in client widget.
