[share-bar] make it a (improved) GtkInfoBar

1. Instead of a GtkBox. This fixes the different appearance of the bar
from the rest of the stock Nautilus bars.
http://git.gnome.org/browse/gnome-user-share/commit/?id=1cfba2417317e5059635568cb49e5093e989e4fa

=> Note: Don't use GTK3 functions: gtk_box_new(), gtk_widget_set_halign()
Stick with gtk_vbox_new() and gtk_misc_set_alignment(), for now.

2. share-bar: remove unused nautilus_share_bar_get_button()
http://git.gnome.org/browse/gnome-user-share/commit/?id=71f364b6646a470e829f87bb1f076ca360fc24c5

3. share-bar: make the label property write only
http://git.gnome.org/browse/gnome-user-share/commit/?id=c307a0196399f0ff29be4a7a4fad0a6c43a22e1b

4. share-bar: don't set italic text
http://git.gnome.org/browse/gnome-user-share/commit/?id=05df1dd95aef7b164932d89d91004df264bbdbe4

5. Improve the nautilus cluebar (text more concise and bar more compact)
http://git.gnome.org/browse/gnome-user-share/commit/?id=8ae76ce81119e63ac6fdfdd537d256bf82069e0a

6. share-bar: remove empty finalize method
http://git.gnome.org/browse/gnome-user-share/commit/?id=d1c1de37ba47b723a43c0adff9f78a2fa56e45ae
