EShellView: Add a "view-instance" property.

EShellView now holds a reference to the active GalViewInstance.  Where
applicable, the EShellView subclass is responsible for keeping this up
to date when the sidebar selection changes.

Holding a reference allows EShellView to implement common actions like
"Save Current View" directly instead pushing it on to subclasses.

New functions:

  e_shell_view_get_view_instance
  e_shell_view_set_view_instance
