[imp] Hide text/plain download link

[ssri_abo at u-paris2.fr]

Hello,

When displaying a multipart/mixed mail, containing text/plain & 
application/pdf, IMP shows two download links, one for the text/plain 
attachment, one for the application/pdf attachment.
Is it possible to hide the download link for the text/plain attachment ?

Have tried to 'show' => false for $mime_drivers['imp']['plain'] but IMP 
still show the download link.
