Title: Added the forcedefault option

I added the forcedefault or f option. This allows you to force a gravatar to any of the available defaults even if the user has a defined gravatar image--it will be ingored.

I don't really know what I'm doing, and I've only been doing Ruby for 3 days... but the commit is fairly small, and it works for me.
