Remove JSON sourceHandler

Some weirdness happens when using this with meteor-bower. Probably because we both registered JSON sourceHandlers. Removing the handler means meteor will not generate fonts when the iconfont.json file changes (unless meteor-bower is present), and a meteor restart or an SVG change is needed to trigger the font regeneration.
