[TYPO3-dam] Media types and file types

[Michiel Roos [netcreators]]

Hi Uschi,

Mime is a hairy business . . .

Read up on it here: http://www.iana.org/assignments/media-types/index.html
And here: http://www.w3schools.com/media/media_mimeref.asp

I think we should try to include a 'sane subset' of popular mime types.
