Use protocol-relative URLs

In this commit I've changed every link and resource to use a protocol-relative URL for when (if) Brickimedia uses SSL at any point. The only resources/links I haven't changed are in the PayPal donation button, as PayPal should be secure regardless if a user is using Brickimedia in standard HTTP or with SSL.
