Handle module’s console output

[kennethormandy]

The latest version of Jade is outputting warnings to the console (it might have been before).

This might be part of Harp’s CLI interface eventually, but maybe we want to have some way of sharing these warnings without posting them so many times? On harp compile right now, I get /path/to/app, line 2: Implicit textOnly for script and style is deprecated. Use script. or style. instead. about ten times over when I run harp compile, and it takes three times as long (this could be because of the error rather than the message, I’m not sure).

This would be nice to do for SCSS, too. RIght now, you can use @warn statements in Sass, but they are automatically output to the console by either libsass or Node-sass (I need to look into which).
