`pat-upload` event when all uploads are completed

[petschki]

I though that uploadAllCompleted event tells me, that all uploads are completed -> wrong 🤔

Since this event gets triggered on Dropzone.success, its fired after each uploaded file. The correct event would be Dropzone.queuecomplete. But with this event you do not have the data of the uploaded files. This needs investigation who uses uploadAllComplete and how ... currently greping mockup shows, that its not used at all, since tinyce now has the contentbrowser.

Mainly this is "just" a documentation issue, because all pat-uploadoptions get injected into Dropzone so you can simply use data-pat-upload="queuecomplete: my_complete_function" and register it as window.my_complete_function somehwere in your code.
