Account for SingleQuote in the case statements for the cli, plus some errata

+ Evidently I failed to finish fixing merge conflicts
+ Some of the types that the SingleQuote code mentioned didn't exist according to the build step. I looked around and switched them out for types it LOOKED like they were supposed to be, but someone should probably check this
+ Don't make commits like this; it's multiple unrelated changes thrown together. I'm still figuring out my way around here
