Fixed Maven2 build issues:

* There's a problem with Maven2.1 with build extensions. See http://jira.codehaus.org/browse/MNG-3097. I have found a workaround by defining build extensions in top level POMs. This seems to work fine.

* Use Platform Tools v1.1 everywhere.

* Specify XWiki dependency versions where it was missing
