CLI: Version checking fails with versions of node.js greater than 0.9.x

[HighTechnocrat]

The issue causes the cli to not return a negative value when it finds errors.

Starting from line 320:

//Workaround for nodejs/node-v0.x-archive#1669
if ((!process.stdout.flush || !process.stdout.flush()) && (parseFloat(process.versions.node) < 0.5)) {

Working fix (not extensively tested):

var verArr = process.versions.node.split('.');
var verMajor = parseInt(verArr[0]);

var verMinor = parseInt(verArr[1]);
var verPatch = parseInt(verArr[2]);
if ((!process.stdout.flush || !process.stdout.flush()) && (verMajor===0 && verMinor<5)) {

Same here, node 0.10.5 & 0.11.0. Works with 0.9.9.

Maybe this checking should be removed since there have been 3 major release (0.6, 0.8, and 0.10) that aren't affected by this issue. This would need to accompany a bump in the engine version https://github.com/stubbornella/csslint/blob/master/npm/package.json#L10
