[TYPO3-mvc] Download link with FAL

[Philipp Wrann]

In some cases (depending on hosting/filesystem settings etc) publicUrl can return broken urls because the value stored in the database is physically not requestable on the filesystem. Happens with special characters like white spaces, umlauts or copyright symbols in file/folder names.

In that case the image.uri viewhelper might do a better job.

I am still missing a sanitizer possiblity in the uploads module that you can turn on to replace those characters.
