Better CSS styling with a line rule to separate the preview and the edit fields. More consistent with existing markup.

#367267: Reverting line needed for multigroup support, since it breaks groups until the multigroup patch is applied.

#397578: Uncouple ImageField from custom FileField hooks. Implement ImageField as a dependent widget for FileField.

#387194: Major FileField UI Refactoring. Putting File info side-by-side the preview, hiding fields that are unnecessary before uploading a file.

CSS and Markup changes to make it so that clicking upload buttons doesn't cause unexpected wrapping of text when the buttons are floated.

#303286 by dopry, drewish, moonshine, Add field to file during validation so it is available during hook_file_insert.

make filefield_token depend on token for the idiots who don't realized it won't do anything if token.module isn't installed... even though there is no actual dependency....
