added IT and DE translations for form builder controls

All controls translated into Italian and German, where it makes sense. Some remain in English because they are technical terms.
ATTENTION: Not tested with the current master branch (only with orbeon-4.3.0.M1.201307222118-PE.war) because the builded .war refers to an absolute path. What can we do to eliminate this problem?

Some whitespaces and tabs in the xml files have been removed by my editor, sorry for that.
