0.4.0

• New get_userrights method for getting an array of all user rights that user has.
• New get_user_gender method for getting the gender of the provided user.
• New get_current_user_meta for getting userlists about the currently logged in user. Essentially the equivalent of get_userlists for logged in users.
• Fix all userlist methods to work without supplying a username.
• New get_registration_time method to get when the user registered.
• Update to work with latest version of string-utility.
• Namespaces are now in a hash instead of a bunch of variables.
• Namespace parameters are now actually limited to the valid namespaces constant. It will default to the main namespace (0) if the integer provided is not in the namespaces hash.
• get_random_pages no longer wrongly sets the rnlimit to the namespaces argument rather than the namespace argument.
