If you run a command from Alt+F2 that tries to get a server grab (eg,
xmag), it will fail if it starts up before the run dialog is finished
hiding.
Additionally, the run dialog currently stays focused while it is
fading out, potentially stealing keystrokes (or causing the user to
accidentally launch two copies of a program).
Change ModalDialog.close() to call popModal() immediately
Add a ModalDialog.popModal method, and call that before running the
RunDialog command. If the command succeeds, close the dialog as
before. If it fails, call ModalDialog.pushModal() to put things back
to normal before displaying the error.

1. Both functions leaked the nodes in priv->children
2. st_container_remove_all wasn't properly updating first_child and last_child
3. remove_all() is almost never right since it won't cause signal handlers
on the children to be removed. In the rare cases where it might be needed
the caller can simply use clutter_container_remove().

This is a base class to make it easier to
gain a consistent look for system modal dialogs.
It handles creating a darkened backdrop behind the dialog, setting
up buttons in the dialog, keynav, etc.
