[rox-devel] Extended attributes for MIME type

Hi,

I've attached an experimental patch which implements MIME types as extended 
file attributes, as supported on Linux by XFS and ext2 / ext3 in recent 
kernels. This moves type information from the name to meta-data, like in RISC 
OS and some other systems. The changes are as follows:

+ type_from_path() attempts to read the extended attribute 'user.mime_type'.
  If successful, the value is used as the MIME type. Otherwise the type is
  guessed from the extension as before.

+ There is a new menu item File -> Set MIME type... which leads to a new
  dialog allowing the user to set the value of this attribute.

There are some problems: it isn't possible to set the type of more than one 
file at once, and copying files loses the extended attributes.

Do people think this would be a good optional feature?

James
