Gravatar HtmlHelper added to Round Table : Armory

As part of my efforts around introducing Round Table : Squire, I’ve started a project to centralize useful pieces of code which have application across many projects.  One of these was my code I wrote about some time ago, a Gravatar HtmlHelper extension.  I’ve now centralized that code, the body of which can be seen below, into the Round Table : Armory project on github.  If you’d like the full code, with all the tests, then just head over to the repository and download or clone it.  If you have improvements, please feel free to send me a pull request.
