[E-devel] [PATCH] Shelf Delete Segv.

[Metrics <me...@sc...>]

The patch attached fixes an issue where you can open multiple shelf
delete confirmation dialog boxes for the same shelf and clicking Yes to
more than one results in a segv. This also occurs if you spawn the
confirm dialogs using diff. methods. 

In order to fix this patch, e_confirm_dialog_show now has a callback for
when it is closed, whether yes/no or some other method is used to close
the box.
