Context

Remove Shelley prefix from error types and constructors. Pretty much all code going forward is going to be Shelley based. The Shelley prefix is redundant because there isn't a need to distinguish it from anything else.

Does this need a separate module?

[newhoggy]

I put it separate from the command error because I think command errors should be separate from domain errors. I'm wondering if we should have a separate parent module for command errors.

Merging now. Can refactor later.
