EMailShellView: Open the selected folder ourselves.

This one's a little involved:

 - EMailShellView now obtains a CamelFolder itself in response to
   EMFolderTree::folder-selected signals.  Uses EActivity to do so.

 - Revise EMFolderTree::folder-selected signal arguments to be more
   useful: emit a CamelStore object instead of a folder URI.

 - Also revise EMFolderTree::folder-activiated signal arguments the
   same way while we're at it.

 - Remove the "folder_uri" argument from e_mail_reader_set_folder().
   If you have a CamelFolder object you can obtain the URI string by
   calling camel_folder_get_uri().
