backlinks as rename page

As we use the xwiki2.0 syntax, we found some bugs as following:
1. As we rename the XWikiDocument, the backlinks can be only changed in xwiki1.0 syntax without under xwiki2.0, because the source only judge the logic of xwiki1.0 in
com.xpn.xwiki.content.parsers.DocumentParser
2. If page1 has an attached file which is imported in page2 through "attach link". As we rename page1, the link cannot be changed to new url in the page2 automatically.

THANKS.
