opts are not passed through to node-sass.renderSync

[mkoryak]

docs say "opts - optional options hash passed through to node-sass.renderSync"

but they are in fact not. only the paths from opts are passed through

Hi @mkoryak ! We can fix this.. out of curiosity, what option would you like to pass through?

[mkoryak]

I would like to pass through:

precision: 8
sourceMap: true
sourceMapContents: false
sourceMapEmbed: true
sourceMapRoot: "."
onError: (err) ->

mostly the source map stuff, but precision is important for bootstrap. I can make a PR if you would like

Also, can you cut a new version once this is fixed please?
