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
// widget_image.ysl2
widget_desc("Image") {
longdesc
||
If Image widget is a svg:image element, then href content is replaced by
value of given variable.
||
shortdesc > Image display
}
widget_class("Image")
||
frequency = 5;
dispatch(value, oldval, index) {
if (index == 0) {
this.given_url = value;
this.ready = true;
this.request_animate();
}
}
||
widget_defs("Image") {
| given_url: "",
| ready: false,
| animate: function(){
| this.element.setAttribute('href', this.given_url);
| },
|
| init: function() {
| this.animate();
| },
}
