Show all editors on view
I overrode Item's _revlog method on Text class, changing the editor's field to show all editors from the page, taking that from the metadata's extra field. Fixed wrong conversion from string of anonymous users (without userid). Updated mobwrite to last svn trunk (only small changes). Also, started working on giving a visual feedback when saving without exit the editor page. I'm creating a new "modify" to be used by mobwrite to commit the changes.
