How to add custom translations for free text labels
===================================================

1. open the source file of the language you like to add a translation for (e.g. FreeText_de.ts for the German translations)
2. add a new message block as child of the context tag
    ```
    <context>
        <name>QObject</name>
        
        <message>
            <source>source string which needs translation</source>
            <translation>the translation of the source key</translation>
        </message>
    </context>
    ```
3. repeat this for all language files which should provide a translation for the source string
4. run the tool `lrelease` which is part of the Qt-Framework tools in order to compile the translation source files *.ts into *.qm files.
    ```
    > cd languages
    > lrelease FreeText_en.ts FreeText_de.ts
    ```
5. now *.qm files are present which contain the compiled translations
6. When the text in the free text label has a translation, the translation text is shown, otherwise it used the source text.
