[patch] [bug 376952] Fix wrong spinner size in 2nd window, and sync spinner code

[Christian Persch <chpe gnome org>]

Hi,

attached patch fixes the spinner size being wrong in each window opened
after the first window [bug
http://bugzilla.gnome.org/show_bug.cgi?id=376952] and also brings the
spinner code up to date with the latest code in epiphany, which fixes
bug http://bugzilla.gnome.org/show_bug.cgi?id=382207 and bug
http://bugzilla.gnome.org/show_bug.cgi?id=374623 .

Ok to commit?

Regards,
	Christian
