Dull the errors
This resolves #426
Dearest Reviewer,
I have updated the error messages to use say_status at the shell level. I have also changed say_status to print the message in bold. I do think it looks nice but it does have the side effect of making some seemingly unrelated text bold. I do think it looks better bold but it is also very easy to revert. I have included examples of both.
Thank you,
Becker
Bold: Note the usage is bold.
