Renaming @Produce to @Publish. #42


...including all class, variable and method names, and documentation where appropriate.

I've ran mvn clean verify and all unit tests locally - everything seems fine. I've also signed the contributor's form on Google Docs.

This is a fairly big change - not just in terms of the API but also the number of files touched. As such this could interfere with other people's pull requests. I suggest identifying what pulls should be accepted before this, and I'll update accordingly.

The one area I haven't touched is the documentation on the index.html docs as this already has a publishing section. I feel we should discuss what to change this section heading to given the nature of this pull. My suggestion is changing it to posting

Please send me an @ - reply if there's anything else that I've missed.
