All set-masterkeyN commands fail because Titles are not initialized yet

[cdriper]

Script exits with unhandled exception if you try to change master key (any switch like "--set-masterkey4").

Traceback (most recent call last):

    if self.titleId.upper() in Titles.keys() and Titles.get(self.titleId.upper()).key:
  File "lib\Titles.py", line 99, in keys
    return titles.keys()

Possible fix (for a single case):

if args.set_masterkey5:
   initTitles()  #  add this line 
   initFiles()   #  add this line 
   f = Fs.Nsp(args.set_masterkey5, 'r+b')
   f.setMasterKeyRev(5)
   f.flush()
   f.close()
   pass

yes that was the fix, I committed to repo thanks.
