error messages and autocorrect?

[ezzra]

regarding the changelog, there should be smarter error messages and an autocorrect function, but still when iam using more_magic=True I will get only the usage message returned and a meaningless message already reported in #5

@ezzra Better error messages are a great goal - the autocorrect felt sketchy to me but seemed useful, so I feature-gated it. I think #14 might help with inspectability / maintainability, the current parser is.... rough.

I just removed the more_magic feature in #51 so now this is a plain old dupe of #5 (but I agree the error message should be better)
