Chrome browsers sort the properties, but Firefox leaves them as defined.
Changed the code to put the elements in an simple array (json array) instead of
associative arrays (json objects) so that the elments are not reordered.

regular array of items, not as an associative array with the id as key
* added dockblock to help the IDE with the return elements for the exports
* moved the protected _jsonBoolean() method to the Cana_Table as it's something to be used in different models
* moved the protected _mergeWhere() method to the Cana_Table as it's something to be used in different models
* use the _mergeWhere() to show the inactive dishes in the admin
* use the _mergeWhere() to show the inactive notifications in the admin
