Matthias Clasen 624ec0fb7d Add a style class for context menus 
Attached widgets inherit from the style of the widget they are
attached to. This can sometimes have unintended consequences,
like a context menu in the main view of gedit inheriting the font
that is configured for documents, or the context menu of the preview
in the font chooser coming up with humongous font size.

To fix this problem, we introduce a context menu style class
and use it for all menus that are used like that. The theme
can then set a font for this style class.

* @short_description: Functions for working with GIO
* @Title: Filesystem utilities
*
* The functions and objects described here make working with GTK+ and
* GIO more convenient.
*
* #GtkMountOperation is needed when mounting volumes:
* It is an implementation of #GMountOperation that can be used with
* GIO functions for mounting volumes such as
* g_file_mount_enclosing_volume(), g_file_mount_mountable(),
* g_volume_mount(), g_mount_unmount_with_operation() and others.
*
* When necessary, #GtkMountOperation shows dialogs to ask for
* passwords, questions or show processes blocking unmount.
*
* gtk_show_uri() is a convenient way to launch applications for URIs.
*
* Another object that is worth mentioning in this context is
* #GdkAppLaunchContext, which provides visual feedback when lauching
* applications.
