Bump to 0.3.0, support Windows 10 detection/usage without requiring 8.1 tooling as well

[sgtcoolguy]

• We now detect 8.0/8.1 and 10 in parallel. Before we'd look for 8.0/8.1 first and if we didn't find one of those we wouldn't try to get win 10.
• Should be slightly faster detection now because of that?
• Mark 8.1/8.0 supported flag as "false" if we can't find the deploy command, that means by default Windows 10 will be "selected" if we find entries for 8.1 but not the tooling.
• Tested by removing my windows 8.1 SDK/tooling through VS2015 Update 1. It actually keeps some stuff around (like XapSignTool), but removes the AppDeployCmd and in that case we list 8.1 in our entry but as unsupported and 10 is chosen as the preferred/selected.

Looks good to me.

I found a issue in different area:
https://github.com/sgtcoolguy/windowslib/blob/TIMOB-20198/lib/wptool.js#L761

• result is not defined at emitter.emit(result || 'error', err)

function (next) {
    if (options.appGuid) {
        guid = options.appGuid;
        next();
    } else {
        getProductGUID(appPath, options, function(err, productGuid) {
            if (err) {
                emitter.emit(result || 'error', err);
                return next(err);
            }

            guid = productGuid;
            next();
        });
    }
}

Otherwise ok to merge, feel free to self-merge this once the issue above is fixed.
