Please add an option to exclude spelling errors from status bar "Errors" count

[rrthomas]

I do aspire to have zero spelling errors in my files, but it's not a top priority. Even with workspace dictionaries, I don't always manage to get my spelling errors down to zero in code or documentation.

Hence, it would be good if I could remove spelling errors from the PROBLEMS panel and Errors status bar count, without disabling SpellRight.

Thanks for SpellRight!
