Timer field to define how to redirect

I think it'd be useful to have a timer field that controlled how the field work, specifically:

• timer = 0 - does a regular drupal_goto()
• > 0 - loads the page and uses either a meta refresh (using drupal_set_html_head()) or a JS call to redirect to the new URL. This would allow for having a splash page before the redirect (useful for disclaimers before redirecting).
