Generate status RadioButtons in status selection dialog from string-array

This changes StatusPickerDialogFragment to generate the RadioButtons for status selection from the string-array mediaStatus_User. This makes it show the correct status strings: "watching" and "plan to watch" for anime and "reading" and "plan to read" for manga instead of just "in progress" and "planned".
