Language translation support

We are supporting language customization in terms of modifying two of the script libraries. Since this is the developers product, which can be integrated to whatever database, this seemed as the most practical way of achieving multilingual support.

These libraries (SwIntOfficeMsg and SwCoreMsg) need to be prohibited for design refreshes, but this is not a big problem, because those libraries are not updated very often anyway.

When they gets updated, these are usually just few lines of code, which we document and give guidance on what needs to be done in order to update your custom SwIntOfficeMsg and SwCoreMsg library.
