Allow embedding of external videos and Google things over HTTPS

[François Marier]

Our removal of httpswwwroot in bug #646713 means that any external content must be available over https. Blocks that need fixing:

- external video
- google apps

Greg Hanley says:

"I just recently moved our site from always https to only login, because when students embed video from outside of the site (which they are encouraged to do to save file space and to take advantage of other resources) Internet Explorer will block the content every time you reload the page. It also looks like it is blocking the new Google Apps block type, even if the provided url/embed-code has https in it. As Iñaki Arenaza mentioned, we use LDAP for logins that can't be allowed to pass in clear text so HTTPS is important. At least 25% of our users use IE and it becomes very irritating having to constantly confirm "show all content" when editing a page or browsing a collection.

Some of this might be mitigated if the googleapps and externalvideo block types took into consideration the site's SSL status and embedded the content with https sources when available (both YouTube and Google Apps seem to support embedding over https)."
