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.

Modbus extensions requires native Modbus RTU/TCP library to be installed nearby Beremiz.
Following directory structure is expected:
<Parent directory>
  "beremiz"
  "Modbus"

If Modbus library is installed elsewhere, then place corresponding paths
in CFLAGS/LDFLAGS in project settings.

For GNU/Linux to install Modbus library in parent directory run following commands:
$ hg clone https://bitbucket.org/mjsousa/modbus Modbus
$ cd Modbus
$ make

After that Modbus extension is ready to be used in Beremiz projects.]]></xhtml:p>
