I've replaced all 7.2.0 occurences and fixed a bit version headers of documents. Dan - please review the changes and check if anything is still missing.

Btw. I've also created an ad-hoc Jenkins job to quickly regenerate Server documentation on docs.tigase.org : http://build.tigase.org/jenkins/job/tigase-server-documentation/

Reviewed changes and documentation, added some missing fixes as well. Documentation included in server does not include mentions to v7.2.0 now. May need to check components, but I doubt that is an issue.
