close Pyro socket after daemon stop


without that socket port is open after daemon shutdown.
As a result if you restart daemon with new settings (service name, for example),
it can't listen on already used port and opens the next free TCP port
regardless of requested settings.
IEC 61131-3
===========

    IEC-61131 is a normative document provided by the standards organization IEC
    (International Electrotechnical Commission) and describing a standard for
    implementing programmable controllers.


    The part 3 of this document (commonly named IEC 61131-3) specifies syntax and 
    semantics for programming language for programmable controllers. Beremiz
    implements all the languages described in this document.

PLCopen TC6
===========
   
    PLCopen is a vendor- and product-independent worldwide association defining
    international standards for various topics related to control programming.
    For this purpose, PLCopen has 6 technical committees.
   
   
    The goal of the sixth committee (TC6) is to define a standard file format, 
    based on XML, for exchanging programmables controllers programmed using 
    IEC 61131-3 languages. Beremiz uses this file format for saving the PLC
    programs of projects.
