gulp-ruby-sass made easy

• Only add the Sass file that you want to compile to gulp.src(), like 0.5.0
• Environment files like Gemfile and .ruby-env are read automatically
• container option if you want to use gulp-ruby-sass in multiple streams at once
• Emits sass, bundle, and spawn errors (compilation errors, missing Gemfile, etc.)
• Sourcemaps write correct relative path for all files
• Support for sass --compass option
