New

• A 'resize' event is emitted when the virtual-scroller size changes
• New refs: vm.$refs.itemContainer and vm.$refs.items for the container elements.

Improved

• buffer is now applied around the pool.
• Some unnecessary updates are now skipped.
• The previous items are removed the next frame. This fixes nasty issues when dealing with items that change their height multiple times or contain horrible things like iframes.
• The first update is now skipped if the scroller has been rendered on the server.
• Source code: Some syntax and code style changes.
