• Update the glibc source data to the data from glibc 2.27.
• Added documentation for this glibc data.
• Reformatted the DateTime::Locale::FromData docs.
• Added a new DateTime::Local->register_from_data method. This replaces the old custom locale registration system with something much simpler. Instead of providing a new class you simply provide a hash of data for the locale and it becomes available for use via DateTime::Local->load. Implemented by Ryley Breiddal. PR #21. Addresse GH #19.
