Fixed PHP warnings in translatable_get_form_values() and translatable_set_form_values().
Fixed node edit redirects to wrong source node.
Fixed incomplete access check for node translation callback.
Fixed wrong translatable_find() conditions to find an existing translation.
Fixed translation language not properly set when editing a source node.
Added hook_translatable_form_alter() to allow modules to alter the final node form.
Fixed menu items for nodes are created in the wrong language.
