[Flow] Upload multiple files

[Christian Eßl]

Too bad. I overlooked that due to security concerns you can't access the full path of a file-input. So I can't simply convert the user-input of a multiple-file-input into several single-file-inputs on client side.

This means I have handle things on the server side. Teach TYPO3 Flow to handle uploads from a multiple="multiple"-input. But where is the uploading of files handled? I looked at the TypeConverters but couldn't find anything related to uploads there.
