Fix an exception on wx-3.0-gtk3 in PLCOpenEditor when generating ST files.
On Python2.7 with WX3.0 and GTK3, an assertionError rises on generating a ST file if the name is already set. The first generation works without problems, if you generate the file a second one, PLCOpenEditor tries to open the file
save dialog with the pre entered name from last run. Then the following assertion pops up:
PyAssertionError: C++ assertion "volDummy.empty() && pathDummy.empty()" failed at ./src/common/filename.cpp(568) in Assign(): the file name shouldn't contain the path
This fix reduces the filepath of the ST file the to the filename. Now it works fine.

<xhtml:p><![CDATA[Communication between Beremiz and PLC runtime isn't bound to any specific protocol and could be extended by writing corresponding connector (see 'connectors' directory).
Beremiz reference runtime implementation supports PYRO and WAMP protocols.
This example shows how to use Web Application Messaging Protocol (WAMP).
WAMP can be used to build distributed systems out of application components which are loosely coupled and communicate in real-time. No direct connection between IDE and PLC are necessary.
WAMP is in a process to be published as official IETF standard. Draft specification is already available on IETF website.
To use this example you need WAMP router and standalone running Beremiz_service.
1. See README file in project's directory with detailed instructions for
setup Crossbar.io, router for open Web Application Messaging Protocol (WAMP).
2. Run crossbar
3. Create service working directory and copy wampconf.json from project_files to created directory
4. Run Beremiz_service:
./Beremiz_service.py -x 0 <working directory>
