[banshee] Add Makefile/intltool hook for *.addin.xml i18n

    Add Makefile/intltool hook for *.addin.xml i18n
    
    If you rename the .addin.xml to .addin.xml.in, it will be automatically
    parsed for translatable strings (elements and attributes starting with
    an underscore).  Then, you can access the translated elements with
    eg Catalog.GetString (addin.Name).
