K4 Reginfo - Add Timezone Function

Hi all,

First, a big thanks to the developer :iloveyou: of the Reginfo update. It works well and gets the job done easily. It is very convenient for places where Wi-Fi/Whispernet is not available.

Also, I have a request. Please include the (optional) facility to change the device timezone as well.

If the timezone is not set correctly then the books don't get arranged in the proper order. Of-course the TZ can be changed by running commands via the USBnet but non-technical people may not be able to manage it.

Thanks :) :2thumbsup.
