If the problem with https://github.com/cocos2d/cocos2d-spritebuilder/pull/1306 is that SB doesn't support untagged resources yet and the templates don't include 1x and 2x art, we can change the export settings of the template project to export all of the explicit resolutions. Then we don't need to add a hack to Cocos2D to work around it.
