Date transformation function requested

I've added a scripting function $fmtDate(fmt,x) to format raw timestamps into human-readable dates using a user-defined format string with Mp3tag v3.36-beta.2.

For example, the date 2001-02-03 04:05:06 can be created using yyyy-MM-dd HH:mm:ss where

Format Output
yyyy 2001 (year)
MM 02 (month)
dd 03 (day)
HH 04 (24-hour)
mm 05 (minute)
ss 06 (second)

If the second parameter (timestamp) is omitted, the current timestamp is used.
