BREAKING CHANGES

• GlDisclosureDropdown: Action items are now determined by the lack of an href string. An item with an href string is rendered as a link item, whether or not it has an action callback.

Before this change, if an item had both an href and an action, it would render as a button. Now, it would render as an anchor.

• GlDisclosureDropdown: The this of the GlDisclosureDropdown action callback is now undefined rather than the item it's attached to. It now receives the item as a regular argument instead.

This makes it more similar to the action event that's emitted by the component, such that the same function could be used in either way.

This also means that the same callback can be attached to all items, instead of requiring a unique callback for each item.
