Title: Make sure protocol gets passed to site_image_url

- Currently, once protocol was set, the config option would be ignored since already set.

- Don't have setters ignore input if instance variable was already set.

- Added new API option for protocol

- Falls back to // for protocol if non passed, will work for both https:// and http:// depending on the domain the page is on.

- html_safe isn't present without active_support
