Functionality fix

Hi, we (company I work for) found that after coping page it looses it's parent. As a result we preform fix, and few other issues that came out by the way. This version was checked against confluence 4.3.7. Please, consider pulling it and release as a new version so everyone can benefit from it.

Fix: now it actually uses logging facade(log4j), not System.out.print; 
Fix: now it really does copy the newest attachment;
Fix: replaced all deprecated methods with their newer versions
NEW: error handling when page with attachment has missing attachment
NEW: added good base to perform full i18n translation.

Best regards,
Augustin
