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

<xhtml:p><![CDATA[This example shows logging functionality in Beremiz.

Here are shown two ways of logging:

- from IEC PLC program;

- from python extension.

In IEC PLC program every third second (beat) new message is generated and put in PLC log.

See function blocks below.

Every 15 seconds status of PLC program is put in PLC log from python extension.

For more information about logging from python look at 0.x: py_ext_0 implementation in project tree.
