[Dx4win] Suggestion for "ease of use" improvement

[Larry Alkoff]

The backup files dx4win.ctb and dx4win.dxb are deleted when dx4win exits normally.
My request is that these files should _also_ close when alt-s is typed
since after alt-s the log and cty files are up to date.

This will eliminate the problem when dx4win closes unexpectedly
and upon reloading asks if you want to save the backup files.
Since I don't remember at that time if I alt-s'ed or not I have to look at both 
the current file and saved backup.
They are useless at that time if alt-s saved the last modifications
and deleting them at alt-s time would save a lot of time and energy.
