CED, CEI, CM1 box sets

[kodawah]

not sure if CM1 is right since the oversized cards are in a separate edition (OCM1)

There were some issues I needed to fix post-merge:

• ocm1 is a separate set on mtgjson, so oversized box should go there
• Will-O-The-Wisp -> Will-o'-the-Wisp
• Nevinyrrals Disk -> Nevinyrral's Disk

At some point I'd like to setup a CI that can deal with it automatically.

ah thanks for fixing those, happy to the care of them at the next review
