Removing public link for "My Proxies"

This is something that may not be ready for April 15th, so I'm
removing the ear mark for it.
Adding initial Group structure
Tweaking layout and information
Adding Hydramata::Group::Form

There is an underlying pattern that I'm working on determining. I'm
working hard to avoid using Rails callbacks as they are a very
frustrating anti-pattern.
Adding Group.new_form_for

Also moving the module declaration up a level; this provides some
namespacing shortcuts
