LP-E12 cover split

I redesigned Snafky's cover a bit which seemed too tight and split the side to make it flex on a bit. That's all.

UPDATE: Added another version (w/logo) that better fits the Canon branded batteries as the first one better fits the Bonacell brand batteries from Amazon https://www.amazon.com/gp/product/B01N4MZ8SD/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
