Support fields of type "file"

Currently this module only supports fields of type "media" - however this is now deprecated in Media 2.x, see http://groups.drupal.org/node/215218 and most specifically:

Site builders are recommended to use the core Image and File fields for handling file and media (and use the 'Media file selector widget for those fields) rather than using 'Multimedia asset' fields.

Adding a file field with a media selector widget is not compatible with this module, and since this is now the only currently-supported way to add media fields to content types using Media 2.x, Media Embedded would become the most awesome module ever if it kept up :)
