Description:

a FileDialog with (image) preview.

It knows a number of default file types to generate a preview
(which is typically a bitmap image, but may also be text).

For your convenience, it is also pluggable so users of this dialog can
define a previewGenerator, which gets the fileName and can provide an image or text.

Typically to show the author, revision info etc. of the selected file.
