User account, home directory, ssh keys, and keygen functionality are inseparable

[martinb3]

Per #42, #73, #74, all four resources are touched no matter what you're actually changing. For example, for this action:

action :modify do
  user_resource :modify
  dir_resource :create
  authorized_keys_resource :create
  keygen_resource :create
end

There's basically no one way to user_resource, dir_resource, authorized_keys_resource, or keygen_resource independently. Thus, modifying any of them ends up modifying all of them. This especially unpleasant with .authorized_keys as doing anything to a user wipes the file, even if you're performing an unrelated operation.
