negation-pseudo-class-bug & fix suggestion

[HIGGO36]

While using your tool to unminify a min.css file, I noticed some errors that were created in the final deminified file, which all dealt with the "negation pseudo-class".

So, I found the issue within the 'cssunminifier.js' file located in the /lib/ folder.

My suggested fix: (Look at the code around line 24, .replace(/\n ([^:]+):\s*/g, **'\n $1:')** )
// I removed the additional unnecessary spaces

Your current one has: .replace(/\n ([^:]+):\s*/g, '\n $1: ')

Beginning around line 17 of ' cssunminifier/lib/cssunminifier.js ' file:

Replace current code with:

code = code
        .split('\t').join('    ')
        .replace(/\s*{\s*/g, ' {\n    ')
        .replace(/;\s*/g, ';\n    ')
        .replace(/,\s*/g, ', ')
        .replace(/[ ]*}\s*/g, '}\n')
        .replace(/\}\s*(.+)/g, '}\n$1')
        .replace(/\n    ([^:]+):\s*/g, '\n $1:')
        .replace(/([A-z0-9\)])}/g, '$1;\n}');

  if (tab != 4) {
	    for (;tab != 0;tab--) { space += ' '; }
	    code = code.replace(/\n    /g, '\n'+space);
    } 

If it helps, here is some code that will produce errors without the suggested fixes from above.
