Subject: Add command line option to write output to stdout

Adds the command line option pair -w/--write.
These options indicate that the output should be written to standard output,
rather than being posted to coveralls.io, which may be useful for debugging,
mixed-language codebases (e.g. node addons with C++ code) etc.
