2.x datastream

[Snugug]

Reroll of #225

• Passes file as data instead of passing file name
• Updates error message handling to show real file name instead of stdin
• Reimplements includePaths handling so we can pass file data directly
• Massages source maps to replace stdin and stdout with the right file names
• Resolves gulp-sass discards changes from earlier in the pipeline when generating source maps #158, Double check for opts.includePaths #202

Do we think we should have tests specifically for the issues going on in there? I've done some basic tests to determine if it works, but nothing more in-depth.

lgtm, an opinion @dlmanning ?

@dlmanning @Keats Once we get this merged in, I think we should release a beta, maybe bump node-sass to beta in package.json.

👍 I'll publish a beta

@Snugug @Keats Should be able to install the alpha release now with npm install gulp-sass@next
