javadoc for taverna-osgi

taverna-osgi javadocs should be generated published on the website - particularly as there are various *-api modules.

I've started the upload to http://taverna.incubator.apache.org/javadoc/taverna-osgi/ - but I think the javadocs themselves might need a quick click-through to see they are not too outdated/empty/wrong.

Many of them will have @author David Withers as he did most of this work as part of Taverna 3 consultancy - but should we remove or keep these kind of @author tags under ASF? (David not a committer on Apache Taverna)
