Files type, handler, fast prototyping entry and view

[onzag]

The files type has no handler and no fast prototyping entry nor view.

While this is not currently very relevant because the text type can inject the file property as media, and that's the best way to utilize such property, there should be a handler and fast prototyping entry and view in order to maintain consistency.

It should be similar to the file type but allowing to display lots of files.
