XWIKI-12: Reorganize directory structure to match Maven2 best practices and cleanup build

* Moved build-tools in xwiki-tools/build-tools
* Added deployment configuration to deploy our artifacts to maven.xwiki.org for now (in the future we'll need to deploy to Object Web's snapshot repo). I've deployed snapshots versions of all our artifacts.
