31000	Match @import rule and url() statement exclude of the css comment /* */ in the css file source code, during the run collectstatic command	Tomáš Zigo	nobody	"I use some extrenal js lib assets in the my django project (automatically installed by the bower js package manager).

Some css source code has {{{url()}}} statement inside the comment {{{/* */}}} with wrong relatative path to img/font.

During running command {{{python manage.py collectstatic}}} I get error message.

The CSS file 'colorPicker/index.css' references a file which could not be found:
  colorPicker/_blank.gif

Please check the URL references in this CSS file, particularly any
relative paths which might be pointing to the wrong location.
}}}

{{{ url('_blank.gif') }}} statement is inside comment in the css source code.

Problem is that {{{@import}}} rule and {{{url()}}} statement are checked in all css file source code content, include code between css comment {{{/* */}}}.
( regex pattern for the match rule/statement {{{ django.contrib.staticfiles.storage.HashedFilesMixin.patterns}}})

I write patch which match this rule and statement only outside of the css comment in css file source code.
