Show success message after upload has finished

[susnux]

Problems:

1. The upload progress bar vanishes after the (failed or succeeded) upload so you do not get any confirmation.
2. Starting multiple uploads are processed in the same progress bar -> no individual confirmation if one of them already is done.

Solution:
Show a success toast for fully done uploads.

e.g.:

• file.txt was uploaded
• folderName was uploaded
• file.txt and 3 other files were uploaded (if you choose multiple files)

Shouldn't this be left to the apps using the component ?

[susnux]

I think it is up to the app using the API. But the component needs to do it itself as the app does not know when a specific upload has finished only when some parts of it or all uploads have finished.

So its not part of our uploader API but part of the UploadPicker component.

Alright, make sense then! :)
