Stop overriding the app css_compressor setting

[byroot]

I fail to understand why this gem is doing so, but it's preventing users to configure the CSS compressing as they will.

@bolandrm could we remove it, or am I missing something?

Hey, looks like a bug. I believe the only line that needs to be removed is Line 56.

No, because nil mean you don't want any compressor. For example we don't want compression in our test environment.

After removing line 56, the API becomes the same as sass-rails. sass-rails appears to force compression in the test environment.

God you're right. Let's do like sass-rails then.

But ping @rafaelfranca: Do you think this is a same default: https://github.com/rails/sass-rails/blob/master/lib/sass/rails/railtie.rb#L69-L76 ?

@byroot I can incorporate this PR:

https://github.com/rails/sass-rails/pull/338/files

so that we allow no compression in the test environment.

Sounds like a good idea. Maybe we should wait to see what sass-rails does of this PR?

In the meantime I updated this PR to copy sass-rails behaviour, and I fixed the test suite.
