Avoid usage of localized strings before initialization during import in many modules

Avoid usage of localized strings before initialization during import in many modules

This happens if import is done before i18n setup
(InstallLocalRessources()).
This affects PLCOpenEditor mostly. Beremiz IDE is free from this issue, but moving
initialization from import should make modules more robust.
Otherwise execution result depends on where and when import was done
and this is not a good thing.

Some modules (ConfigTreeNode, features, CodeFileEditor related
classes) still have this, but they are used only in Beremiz.
Most problems result in non-working internatialization.
In some cases (VariablePanel) there is backtrace, because localized
key is not found in non-localized dictionary.

<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.
