Feature Request - Meta Robots Support

Hi Bjorn,

It'd be really nice if you could add meta robots support, so I'm just adding it here as a feature request.

It was mentioned on Get Satisfaction about a year ago in more detail: https://getsatisfaction.com/addonbakery/topics/can_you_add_2_fields_to_seo_lite_i_think_they_are_useful

Thanks,

Stephen
