String changes in EOG

["Lucas Rocha" <lucasr gnome org>]

Hi all,

The following string changes were made in EOG:

- Removed the "Image Collection" tab from preferences dialog.
Therefore, all the strings from this tab are not in the catalog
anymore;

- Added a Side Pane menu item in "View" menu. Corresponding GConf key
added as well.

Cheers!
