* Replaced custom SQL query in Comment.remove() with code using new Membership.comments collection
* Removed obsolete Sql.COMMENTS statement
* Added getConfirmText() method to Comment, File, Image, Layout, Membership, Poll, Skin and Story prototypes – which is used in HopObject.delete_action() for more convenient feedback about what is going to be deleted (fixes issue 37 for now)

* Removed obsolete Layout.getTitle() method
* Disabled translation in HopObject.toString() methods
