Gapcoin's first record in the 20000-24998 range, shift 920

@j0nn9 - Is it possible to get 20000-24998 added to the gapcoin.org record range?
EDIT: Nevermind, looks like it works!

Also for anyone interested in hunting for larger overall length gaps, here are some settings that have worked for me (your mileage may vary).  As time goes on I'm starting to think in some ways larger shifts can be tuned for larger performance (notice I set the fermat thread to total thread ratio very high on these).

Shift 702 on an i7 (8 cores)
./gapminer-cpu -o 127.0.0.1 -p 31397 -u ***** -x ***** -t 7 --shift 702 --crt crt/crt-22m-704s.txt --fermat-threads 5 --sieve-primes 450000

Shift 920 on a 4 xeon server (16 cores)
./gapminer-cpu -o 127.0.0.1 -p 31397 -u ***** -x ***** -t 18 --shift 920 --crt crt/crt-22m-928s.txt --fermat-threads 15 --sieve-primes 300000
