[PVRCNC] Database Cleanup

[Alan Knight]

Thanks for the feedback everyone.  As I suspected, about half of the list,
maybe more, are silent keys.  A few have new callsigns.

FYI, it wasn't my intention to drop anybody from the roster.  I just wanted
it to be a little more accurate.

I should have some new 5M scores uploaded soon.  We had problems with the
PVRC server last weekend and been busy at work during the week.
