[Libreoffice] [PATCH] gtk toggle buttons (libs-gui)

Hi,

Here is a patch to fix gtk toggle buttons, and it cleans up the code a
little too.

"togglebutton" detail is not standard, and caused some bugs with the
Ambiance theme, see this bug:
https://bugs.freedesktop.org/show_bug.cgi?id=33473
and this page to check the standard details name:
https://webstats.gnome.org/GTK%2B/ThemingInternals
(GtkToggleButton is a subclass of GtkButton)
