[gnome-flashback] Issues with gnome-flashback on Ubuntu 16.04

[Alkis Georgopoulos <alkisg gmail com>]

Hi, I'm trying out gnome-flashback on Ubuntu Xenial 16.04, and I'll like 
to provide some feedback about whatever issues I discover.

1) Two nm-applets appear in the systray.

2) All gnome menus, for example the Applications menu or the Gedit 
menus, have a large (about 20 pixels) gray border around them. 
Thunderbird or pidgin don't have that border. I'm using metacity, not 
compiz.

3) Some dialogs (e.g. the "save before exit?" dialog of gedit) have 
their buttons (Close without saving / Cancel / Save) too wide, so that 
they fill the whole dialog width.

4) I would like to propose that the window buttons are restored to their 
pre-Unity settings, menu/minimize/maximize/close.

Thank you for your work on gnome-flashback,
Alkis
