Host the javadocs for release versions

[eawagner]

I have often needed to point people to the javadocs for some of the classes. Unfortunately, the only javadocs that I can seem to find for mango on google are for 1.1.0.

I suggest we host the javadocs and potentially the xref docs in the calrissian.github.io project so that we point to them.

This would probably apply to other calrissian projects as well.
