1.18:
----

 * Added a simple selection to view multilingual translated entries and return to default language.
   This needs at least a link in your themes navigation bar or a sidebar nugget pointing to:
   "index.php?serendipity[subpage]=customarchives&serendipity[custom_sortyears]=all&serendipity[lang_display]=en"
   for example.
   Then the customarchive form allows to query by lang_display variable too or return to the default language,
   which also wipes this simple new select option.

   is required to enter the metadata that this plugin operates on.
