un_qwk.cpp

If a VOTING.DAT file is received which did not contain offset/location
sections, the vote/polls/etc. wouldn't be imported. Now, when each QWK 'V'
msg hdr block is imported, the corresponding section is removed from the
VOTING.DAT and after all QWK importing, the VOTING.DAT is then parsed
for remaining items/sections and if there are any, imported at that time (in
order in the file, not in the old poll/vote/closure order).
