Wp coding spacing

Still seems to work here, though I can't test everything.

Do we really want to give an option for Comment spam? Isn't that the whole point of this plugin? I would probably remove the options for both comment and registration as they are the main points of the plugin. Everything else is an option. Though I would also tend to remove the choices to enable for contact forms and gravity forms. This is a decision that can be made later and I'll put an issue up for it.
