#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....

tnx.
