RE: Platform specific preferences

[Sergey Grebnov (Akvelon)]

I didn't know we support <platform> tag inside widget. This is great.

But we should also patch cordova-cli ConfigParser.getPreference function to 
handle this case.
https://github.com/apache/cordova-cli/blob/master/src/ConfigParser.js#L82

Before

getPreference: function(name) {
    var preferences = this.doc.findall('preference');
    var ret = null;
    preferences.forEach(function (preference) {
        // Take the last one that matches.
        if (preference.attrib.name.toLowerCase() === name) {
            ret = preference.attrib.value;
        }
    });
    return ret;
},

After

getPreference: function(name, platform) {
    var preferences = this.doc.findall('preference');


    if (platform) { // if specified, we search for platform specfic preferences 
also
        preferences = preferences.concat(this.doc.findall('platform[@name=\'' + 
platform + '\']/preference'));
    }


    var ret = null;
    preferences.forEach(function (preference) {
        // Take the last one that matches.
        if (preference.attrib.name.toLowerCase() === name) {
            ret = preference.attrib.value;
        }
    });
    return ret;
}

Thx!
Sergey

No idea :P. Stumbled upon it when I was doing a recent CLI refactoring.
