Enhance widget to work out-of-the-box

Currently the widget simply works with the plugin, make the widget so developers have minimal effort to implement it on their apps.

Hi!

I was looking forward the avatar upload feature within yii2-usuario, then I walked into this repo.

How about adding https://github.com/mohorev/yii2-upload-behavior to project in order to simplify the development?

If it doesn't suit your vision, I could help, but some guidance will be needed.

Thanks for your work!

@naffiq Thanks for your proposal. We have an issue with adding external libraries as sometimes we got hang on repositories that were removed by their developers. The problem with croppie is that is not fully completed to work out of the box. I'll try to solve my lack of free time and implement it.

Edit: BTW the behavior looks awesome but I would rather create one to work with Flysystem instead.
