Merge pull request #4929 from RosettaCommons/roccomoretti/no_ascii_options
Try to give better feedback with non-ASCII options.
An error that comes up semi-regularly is where someone uses an en-dash instead of a hyphen in Rosetta options. (Certain Word processors like autoconverting things.)
Adjust option parsing to try to better highlight cases where this may be happening.
Additionally, we can handle dos/unix file ending issues in option files by broadening the meaning of 'whitespace'.
