Nautilus UI/String freeze break request

[Cosimo Cecchi <cosimoc gnome org>]

Hi all,

I apologize for the many freeze break requests for Nautilus this
cycle, but I have one last request to commit an UI/string change.
Currently we have two mimetype columns for List view: one (enabled by
default) displaying its description as a (typically long) string, and
another one displaying the "raw" mimetype string.
Bug 683722 [1] proposes to change the default column to use a more
generic and compact string describing the mimetype; for instance, all
the images would be displayed as "Image". The goals are to make it
possible to group objects of the same family when sorting, and to
reduce the horizontal space such a column takes in the default list
view layout. The raw mimetype string would still be available
unchanged as a view option for more advanced filtering.

The patch is available on the bug and introduces a bunch of new
(short) strings. I think this would add a good extra polish for
Nautilus 3.6.
