* Add i18n-maven-plugin to make internationalization easier
This plugin simplifies generating the default translation .properties files from the add-on XML information files.
It reuses the same XStream parsing classes that are used by openhab-core for parsing the binding/config/thing XML files.
It will also keep any existing default translations already present in property files for translations using `@text/`.
Furthermore it will nicely group and sort the translations.
After building this Maven plugin you can use it on add-ons using:
`mvn org.openhab.core.tools:i18n-maven-plugin:3.2.0-SNAPSHOT:generate-default-translations`
