Device Specific Ad Campaigns/Ad Display#358

Add the option for advertisers to select the devices their ads are displayed on.
The options would be: mobile, desktop, both
This would complement the new ad minting app allowing advertisers to build mobile specific campaigns. Campaign setup would show a mobile device preview to ensure better results for advertisers while also improving the ad viewing experience.

Yes, and WOW again. You guys have done some serious planning lately I see. WONDERFUL!
