Removed duplicated code, in the build.xml file, that copied the Crowdin "Messages.properties" files

 - Added a (helper) task ("copy-crowdin-messages-files") that copies the Crowdin "Messages.properties" files (and renames as needed);
 - Changed the targets "copy-zaproxy-crowdin-lang-files" and "copy-zap-extensions-crowdin-lang-files" to use the added task.
