Fix for NodeJS imagemagick module not parsing IM identify output

imagemagick.js

function parseIdentify(input) {
      var lines = input.split("\n"),
          prop = {},
          props = [prop],
          prevIndent = 0,
          indent = 0,
          indents = [indent],
          currentLine, comps;
    
      lines.shift(); //drop first line (Image: name.jpg)
    
      for (i in lines) {
        currentLine = lines[i];
        if (currentLine.length > 0) {
          comps = currentLine.split(': ');
          indent = currentLine.search(/\S/);
          while (indent <= prevIndent) {
            indents.pop();
            prop = props.pop();
            prevIndent = indents[indents.length - 1];
          }
          if(comps.length < 2) {
            indents.push(indent);
            props.push(prop);        
            prop = prop[comps[0].trim().toLowerCase()] = {};
            prevIndent = indent;
          }
          else {
            prop[comps[0].trim().toLowerCase()] = comps[1].trim();
          }
        }
      }
      return props[0];
    };
