Title: Feature/timer

Modeled on the spam hammer plugin, I thought it would be neat to implement another anti-spam measure. ( I guess I really spam questions. ) The theory here being that bots only take a second or two to submit a form, so a counter that delays that should leave mostly humans. Does require JS to work though.
