Nuiton-i18n

This version allows checking whether some key is present, lets i18n return null when i18n's key is not found, and makes the UserInitializer always try to copy files.

This version provides two changes in bundle mojo, mainly for GWT use. The bundleOutputPackage parameters have been added. The addBundleOuputDirParent parameter has been removed.

This version removes all the deprecated APIs from version 2.1, updates dependencies versions, and makes the JSP parser more user-friendly.

This version fixes Java parser performance.

A bug in which parser blocks sometimes did not deal with all files was fixed. The versions of some dependencies were updated.
