Adding back Sass compressor

[guilleiguaran]

Adding back support for sass-rails CSS compressor with config.assets.css_compressor = :scss

Fix #1578 and #1619

cc @chriseppstein: please, can you review this? :)

[dmathieu]

Could you not add the empty spaces line 33 please ?

[dmathieu]

And add a test ?

[guilleiguaran]

Actually I was searching but I don't found any test for compressors, I think I can add some tests for entire file in this or in another pull request

In Line 33 I remove trailing whitespaces :)

This hardcoding approach was removed for a reason. Sprockets needs to provide a public api for adding shorthands for compressors. Something like:

Sprockets.register_css_compressor(:scss, Sass::Rails::CssCompressor.new)

[chriseppstein]

But that would only be for other projects to use. The sass-rails plugin automatically sets this up for you. You're best bet is to remove this line altogether.

@wycats: I recommend this pull request be closed and not merged.

@chriseppstein, I was thinking the same, it needs to provide a public api to register javascript and css compressors, I will work on it.

Then, adding sass-rails plugin to the project fix the error described in #1578 and #1619, right?

[chriseppstein]

@guilleiguaran It's unnecessary configuration. Sass-rails does this automatically. Just remove the setting.
