Release 3.4.6.6

• Fix: WP45, '/wp-admin/nav-menus.php': title of newly added menu item kept one language only.
• Fix: WP45, '/wp-admin/nav-menus.php': double quotation mark in menu label.
• Improvement: Option 'Show language names in "Camel Case"' has been added on Settings/Languages page /wp-admin/options-general.php?page=qtranslate-x#general in order to handle absence of function mb_convert_case, as PHP module mbstring may not be installed by default: WP Topic.
• Enhancement: added preset for Welsh (Cymraeg, 'cy') language.
• Fix: regular expression to detect lang=xx in line preg_match('/(^|&|&|&|\?)lang=([a-z]{2})/i',$url_info['query'],$match) of file qtranslate_core.php: Issue #288.
• Fix: smooth run of wp-cron.php from command line: WP Topic.
• Fix: consistency of option "Hide Content ..." to show single post without 404 error, like it is with single page: Issue #297.
• Fix: Predefined locales are changed to match WordPress locales:
  
  Estonian (Eesti) 'et_EE' renamed to 'et',
  
  Basque (Euskera, in native alphabet, Euskara, in WordPress, both correct) eu_ES renamed to 'eu',
  
  Greek (Ελληνικά) 'el_GR' renamed to 'el',
  
  Finnish (Suomi) 'fi_FI' renamed to 'fi',
  
  Croatian (Hrvatski) 'hr_HR' renamed to 'hr'.
  
  Old .mo files are kept in order not to break the sites that may be currently using them, but they should now switch the locale appropriately.
  qtranslate-el_GR. renamed to qtranslate-el.
  
  qtranslate-es_CA. renamed to qtranslate-ca.
  
  qtranslate-hr_HR. renamed to qtranslate-hr.*
  
  This emerged from Topic #27.
• Languages: Slovak (sk_SK) language preset has been added. Thanks to Andrej Leitner.
