[WIP] SassC support

[bolandrm]

This is very much WIP. Comments on the approach are welcome.

This depends on sprockets master (rails/sprockets#148)

@bolandrm I like the approach you're following in this.

We can add sassc gem commented on rails Gemfile and then the users can un-comment it to enable as alternative to default sass.

I've added :sassc as compressor in rails/sprockets@dc78af8, so it can be switched in https://github.com/rails/sass-rails/blob/master/lib/sass/rails/railtie.rb#L80

[bolandrm]

Thanks @guilleiguaran. Testing this in a rails app. Working out some load path issues.

I hope it will be merge 👍 @bolandrm Will you continue this PR ❓ Or, we should use https://github.com/sass/sassc-rails ❓

sassc-rails works fine, but would like sassc in rails by default

I had some issues with windows and sassc. https://github.com/rails/sprockets/blob/master/test/shared_sass_tests.rb#L117 I tried to fix it, even bought a windows machine. I got hung up on the compilation toolchain and had to move to something else.

I'm interested in getting sassc support in sass-rails, would love to help move this along if possible.

I think sassc had a patch to fix the windows install problems ( sass/sassc#206 ) :D

I'm not sure the state of this branch, but I'd love to see this pushed out to all the gems still using sass :)
