Content-Disposition header may be incorrect for Flash files

Issue Summary

Using filefield to allow an administrator to upload .swf files. Flash (.swf) files are to be viewed by the end user in the browser, via a specialized template which requests the file vie javascript. Using private files ( 'system/files' request ). Currently, the .swf file does not play as the Content-Disposition is set to 'attachment' instead of inline. If the file is requested directly (outside of its template), the browser prompts to download.

For a fix, add to filefield_file_download just after the text or image disposition is set.
if ( $file->filemime == 'application/x-shockwave-flash' )
$disposition = 'inline';
