+ /** \brief Returns a vector of Language Codes
+ *
+ * Languages can be defined with their two or five chars long code.
+ * This methods handles the various ways to set the prefered codes,
+ * honors the environment and ensures that the codes are not listed twice.
+ *
+ * The special word "environment" will be replaced with the long and the short
+ * code of the local settings and it will be insured that this will not add
+ * duplicates. So in an german local the setting "environment, de_DE, en, de"
+ * will result in "de_DE, de, en".
+ *
+ * Another special word is "none" which separates the prefered from all codes
+ * in this setting. So setting and method can be used to get codes the user want
+ * to see or to get all language codes APT (should) have Translations available.
+ *
+ * \param All return all codes or only codes for languages we want to use
+ * \param Cached saves the result so we need to calculated it only once
+ * this parameter should ony be used for testing purposes.
+ * \param Locale don't get the locale from the system but use this one instead
+ * this parameter should ony be used for testing purposes.
+ *
+ * \return a vector of (all) Language Codes in the prefered usage order
