Persian calendar date picker

Hi GT

There are some changes in Wialon UI and we see that UI is changing and Gurtam tries to make the UI modern (while we think the speed of this changes are still very slow :-) ). There was some changes in date picker UI during these years but the Persian calendar date picker is still same and really outdated. It would be great if you apply the default date picker UI for the Persian calendar also. When I change the calendar to Persian, and use the date picker, suddenly, I think I'm in another application as the date picker differ from whole system UI.
