Fixes #1230
Renamed TexturePacker2, moved to new package, added scaling.

The scaling setting scales all images before packing and can pack the same images into multiple atlases with different scales. Eg, you can have a single set of high resolution assets and automatically pack them into atlases scaled down for smaller resolutions.
