Feature request:
In debug mode - print the output of linter commands on both STDERR and STDOUT regardless of which stream is selected in the linter contrib file.

Hi,
My personal story is that I just spent 6 hours debugging an issue with cspell, that I could not see was there because it worked fine in my terminal. The contrib linter file selected the STDOUT stream so I could not see the error being given to SublimeLinter when it ran the command.

I think it would make things a lot easier for people with similar situations to debug if both streams were shown.
