Avoid dictionary initialization during import in PouDialog

Because initialization happened before i18n setup, then it causes later
problems during creating new POU on non-English locales (Russian for example).

Traceback (most recent call last):

<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>
