* Wii U Time Sync was refactored to support the new Wii U Plugin System API, thanks to the wonderful efforts of @dkosmari! With it came a whole lot of new features and improvements.
** A new Auto Update Time Zone feature was added, which will automatically fetch the time from the Internet when the plugin loads. This is similar to manually running the Detect Time Zone option.
*** This is an entirely optional feature, set to false by default. You will need to enable it before it works.
** The number of background threads that run can now be configured with the Background Threads setting. This controls how many NTP servers are queried at the same time.
*** If you stick to the default pool.ntp.org server, you probably don't need to change this.
** There is now more control over notification verbosity. Instead of receiving all notifications or none at all, it's now possible to have a non-verbose level of notifications.
*** quiet means that no notifications will appear at all. (This was effectively false previously.)
*** normal means that only success or failure notifications will appear, but no others.
*** verbose means that all notifications (statistics and such) will appear, useful for debugging. (This was true previously.)
** Opening the Wii U Plugin System menu now reloads the settings from the JSON file, which is useful if you want to run a custom NTP server on-the-fly.
* To account for all the updates, the user interface has some new quality-of-life changes. (Thank you, @dkosmari!)
** Hours Offset and Minutes Offset have now been combined into one setting, Time Offset (UTC).
*** If you are updating from an older version of Wii U Time Sync, your configuration will be updated accordingly.
** Pressing the X button on a setting in Configuration now resets it back to the default value.
** You can now hold down left or right on the D-Pad to set a specific option (particularly useful if you want a specific offset or tolerance, for example).
** The clock shown in Preview Time now updates automatically when focused on.
** If text is now too long to be shown, instead of overlapping other text, you can now use left and right on the D-Pad to scroll.
** All boolean options, such as Syncing Enabled and Show Notifications, can now be toggled with either left or right on the D-Pad.
* A grammatical error which appeared if there were any issues connecting to a server has been fixed.
