Freeze break request for zenity

[Florian Müllner <fmuellner gnome org>]

Hey,

I'd like to request a freeze break for the following zenity bugs:

  https://bugzilla.gnome.org/show_bug.cgi?id=684322 - Add an option to
request dialogs being modal

  https://bugzilla.gnome.org/show_bug.cgi?id=684329 - Add an option to
set a custom dialog icon

Each patch implements a new option without changing existing code
paths, so existing users are unaffected by the change - with the
notable exception of gnome-shell/mutter, which will use those options
for its "Force quit" dialogs if available. In particular the first bug
improves the dialog's usability significantly by tying the "this
window does not respond" dialog to the non-responsive window (though
the designers obviously would like both changes to make it in).

Both patches break the string freeze as well, as they add a --help
description for each option - if that is considered a problem and the
code changes are approved otherwise, it is of course possible to not
mark those strings for translations for 3.6.


Thanks again,
Florian
