This commit changes the plugins that uses angular.element to load
resources directly to instead return a function that runs
angular.element. When the browser runs angular.element('<img>') and gets
a src attr it will fetch the content in the src. This makes the
browser running gb automatically fetch all plugin content that gets
linked even if the user didn't request it.
Maybe we could change our plugin architecture to split the match
function and the generator functions so this could be solved more
elegantly.
