Make costume, sound and sprite tiles draggable.

[paulkaplan]

First step towards share-able, backpack-able costumes sounds and sprites.

Adds the ability to drag the sprite selector item, which is the component shared between sprite tiles, costume tiles and sound tiles. A custom drag layer is used for positioning the dragging asset, which uses its image to drag.

Mid-drag:

Doesn't do anything with dropping... yet.

This is amazing! I noticed a couple things:

• I can't drag a blank costume, or a sprite currently showing a blank costume (or at least, the dragged item was invisible). We should probably handle at least the sprite case. Not sure what it should look like while dragging- maybe just an empty box.
• Slightly weird behavior if the sprite is animating (e.g. forever [next costume]) while being dragged- it updates the dragged thumbnail only during drag moves.

updates:

• Dragging a blank costume or sprite also does not work in 2.0, so no big deal there.
• Animation while dragging is not necessarily a bug?

🎉

Also progress towards being able to rearrange the order of sprites and assets! (#225, #1509)
