[latexila/wip/latexila-next] Don't use gtk_icon_theme_add_builtin_icon() (deprecated)

[Sébastien Wilmet <swilmet src gnome org>]

commit 49c526f0ea3581cccd917cf3609d63ddf87e084d
Author: Sébastien Wilmet <swilmet gnome org>
Date:   Fri Jul 11 17:10:03 2014 +0200

    Don't use gtk_icon_theme_add_builtin_icon() (deprecated)
    
    Use gtk_icon_theme_add_resource_path() instead, which is easier to use.
