Review the project structure of XTS

The structure of the XTS project needs reviewing. Things to look out for:

1. Check for ant build scripts and delete/mavenize as appropriate
2. Ensure all source directories follow the default maven structure
3. Move unit tests into the sub component that they test
4. Ensure consistent with the rest of the Narayana project
5. Ensure all readme files are up-to-date
6. Search for version numbers and check they are up-to-date. For example, some readme files state compatibility with certain (old) version of JBoss AS.
7. General review
