TYPO3 Core

You may think, we can not access the client clipboard, but it's possible by HTML5 :D

You can test what i mean by using github, copy an image into the clipboard and paste it in a comment, the upload is done in the background and then it returns a valid url, which can be used online as well :D

I'd like to have this implemented in the rte, and perhaps in other editors as well, perhaps FAL should get a category clipboard images :D
