epublish 6.x-1.6

Fixed theme functions so module now works correctly with PHP 5.3.

Added email as a 3rd context (in addition to listing and node contexts).

Fix bug where delete deletes all articles from an epublish edition. This is very helpful to people that use epublish in a more manual way not just in the auto generator way.

Change out the epublish per node navigation works so that it is more drupal standard. This means that it looks correct when working with complex layout modules like recipe.

Implement basic views support so that editions and articles are exposed to views. More views support will be coming.
