Subject: [PATCH] Add volume control to current track

Volume it's starting in 100% (Volume value is between 0 and 1), volume sharing between all tracks

Example:

HTML
    <input type="range" min="0" max="100" ng-model="volume" ng-change="setVolume()" title="">

Controller
    $scope.setVolume = function () {
        window.localStorage.setItem('volume', $scope.volume);
        MediaManager.setVolume($scope.volume / 100);
    };
