app: add GTK+ patch allowing controlling combo-box popup style

Browse Source 
Add a GTK+ patch providing a "popup-style" combo-box style
property, allowing to manually control the combo-box popup-style.
Use the LIST style for all combo-boxes in our system-wide gtkrc
file; this only has effect if GTK+ was built with the above patch.

Subject: [PATCH 2/2] ComboBox: add "popup-style" style property
Add a "popup-style" style property to GtkComboBox, which can be
used to control the combo box's popup style independently of its
appearance. This is in contrast to "appears-as-list", which
controls both the popup-style, and the appearance.
"popup-style" is of enum type GtkComboBoxPopupStyle, and can be one
of:
- GTK_COMBO_BOX_POPUP_AUTO (default): use the menu style if
"appears-as-list" is FALSE, and the list style if
"appears-as-list" is TRUE.
- GTK_COMBO_BOX_POPUP_MENU: use the menu style.
- GTK_COMBO_BOX_POPUP_LIST: use the list style.
