merged trunk into lua branch
plugin loading is disabled atm because of a bug reading the files (lua may be the reason). Reading the files in usdx and passing the contents to lua may solve this git-svn-id: svn://svn.code.sf.net/p/ultrastardx/svn/branches/experimental@2019 b956fd51-792f-4845-bead-9b4dfca2ff2c

+ * want to store, e.g., the email address of the child of producer Alice
+ * and actor Bob, that could have key=alice_and_bobs_childs_email_address.
+ * 3. A tag whose value is localized for a particular language is appended
+ * with a dash character ('-') and the ISO 639-2/B 3-letter language code.
+ * For example: Author-ger=Michael, Author-eng=Mike
+ * The original/default language is in the unqualified "Author" tag.
