    Add tool to extract strings from addin.xml files
    
    build/addin-xml-string-extract will pull out nodes from
    .addin.xml files that need to be translated and generate
    a file (data/addin-xml-strings.cs) from which intltool
    will happily extract strings into the translation catalog.
