Previously the `FileInput` widget allowed all file types, which meant the user could select *any* file and then only find out it's not accepted after uploading. This ensures the `FileInput` only accepts the listed file extensions _or_ in the absence of file extensions, restricts to audio/video files as appropriate.

FileInputwidget allowed all file types, which meant the user could select any file and then only find out it's not accepted after uploading. This ensures theFileInputonly accepts the listed file extensions or in the absence of file extensions, restricts to audio/video files as appropriate.While https://github.com/torchbox/wagtailmedia/pull/140/files handled server side validation, this complements that work by restricting the file types on the client side.
