Generate correct default css path for namespaced classes.

[ssemakov]

CSS background property is a shortcut for background-color.
After processing scss background automatically substitute with background-color.
That caused spec to file. Change background to background-color in tests and fixtures.

I see what you're doing here and I like it. This will cope with paths two levels deep.

# Two levels
Foo::Bar.name.underscore.gsub /\//, '/_'
=> 'foo/_bar' # good

But we might as well make it work for any number of levels, which the above code doesn't:

# Three levels
Foo::Bar::Po.name.underscore.gsub /\//, '/_'
=> 'foo/_bar/_po' # bad

This regex will do it and also remove the need for the test because it works with just one level too:

# One level
Foo.name.underscore.sub /^(.*\/)*(.*)$/, '\1_\2*'
=> '_foo*' # good

# Two levels
Foo::Bar.name.underscore.sub /^(.*\/)*(.*)$/, '\1_\2*'
=> 'foo/_bar*' # good

# Three levels
Foo::Bar::Po.name.underscore.sub /^(.*\/)*(.*)$/, '\1_\2*'
=> 'foo/bar/_po*' # good

The method can then be:

def stylesheets
  return @stylesheets if defined? @stylesheets
  [self.name.underscore.sub(/^(.*\/)*(.*)$/, '\1_\2*')]
end

I'm not sure it's even worth memoizing that method.

Right. Thanks for catching this!

Good catch. Thanks for fixing that.
