permission change dialog wait cursor

[Mathieu Lacage <mathieu_lacage myrealbox com>]

hi all,

The attached patch adds a wait cursor to the permission change dialog:
this is very useful if the permission change is done on a big set of
files.

Please, note that file permission change has a timing-related bug which
is fixed in the gnome-vfs patch I sent to gnome-hackers earlier. (ie: I
can send it here if needed). This means that if you try really hard to
play with file permissions, it will randomly not display the correct
permission state.

This patch is against CVS HEAD. It can be applied to the 2.4 release.

May I commit ?

Mathieu
