Adding other plugins

[undsoft]

Hey,

Thanks for the extension.
I wonder how I can add custom Flot plugin.
Let's say I want to install flot.curvedLines.

I do:

composer require bower-asset/flot.curvedLines

Then I create my FlotCurvedLinesAsset, where I register all the files.
I need to reference your ChartAsset as a dependency.

class FlotCurvedLinesAsset extends AssetBundle
{
    public $sourcePath = '@bower/flot.curvedlines';

    public $baseUrl = '@web';

    public $js = [
        'curvedLines.js'
    ];

    public $depends = [
        'yii\web\JqueryAsset',
        'bburim\flot\ChartAsset'
    ];
}

But because of the way you are adding your plugins ChartAsset::$extra_js, all the plugins get broken.
I think it would be better if you had an AssetBundle for every plugin.
