add relativePath property to error object for notification(s) support

[ajschlosser]

This would particularly be useful for use with gulp-notify.

I've also added a corresponding assertions to the respective "should handle sass errors" tests.

Just noticed that this addresses part of #399. If @jlgeering has his own PR ready for this, feel free to close this one--don't want to step on anybody's toes!

Hi @ajschlosser, I just closed my issue, as you already submitted a PR.

Cloud you add the originalMessage property too (also useful for notifications)

      error.originalMessage = error.message
      error.message = gutil.colors.stripColor(message);

or maybe

      error.messageFormatted = gutil.colors.stripColor(message);

=> the goal is to have access to error.message from node-sass

And now that I read my comment ... It could be a separate Issue / PR ;-)

[jlgeering]

forget my last comment, created a separate PR for it: #420

@jlgeering Thanks for the update! Good call on preserving the original message, too.
