Default backup name wrong

[TulipVorlax]

The default path and file name of the backup prefs is wrong :

Code:

{pref_directory,"e:/Users/*****/AppData/Roaming/Wings3D/backup_prefs.txt"}.

This bit of code is found on the prefs file Wings create on exit when no prefs file exist, in that same folder.

I think it should be changed to :

Code:

{pref_directory,"e:/Users/*****/AppData/Roaming/Wings3D/backup.pref"}.

Because the backup function use file ending in .pref (without the "s" at the end).
Another possibility would be to make it use simple txt file like the one Wings use in AppData.
