Bug #5479 : JCR copy and move problems

- fixing the case of the copy that did not work too (history of versions was not respected, i18n was not supported, date of a version was not the one of the original but the date of the copy action !)
- fixing the case of the move
- upgrading the simple document access controller in order to take in account the versions of attachments
- improving the mechanism of universal link associated to attachments
- handling the language content for versioned attachments
