upgrade for v4.5.2 + some small fixes

Some updates for v4.5.2, a typo in the documentation and some fixes so it will pass foodcritic.

the package install process doesn't seem to be able to install an older version.  I'll work on that a bit and give another pull request.  I may also do some format cleanup/consistency updates.  

I also think the ssl password lazy setting should probably be done in the ssl recipe.

Let me know what you think of the below.
I think this may be a quick implementation of the functionality that you were looking for
