show the same spf record for a domain in the dnsrecords and dnscheck output/pages

Browse Source 
before, the suggested records would show "v=spf1 mx ~all", while the dnscheck
page would suggest "v=spf1 ip4:... ip6:... -all".

the two places now show the same record: explicitly listing the configured ip's
(so the common case of a valid message is fast and doesn't require lookups of
mx hosts and their addresses), but still including "mx" (may prevent issues
while migrating to new ips in the future and doesn't hurt for legit messages),
and "~all" (for compatibility with some old systems that don't look at
dkim/dmarc when they evaluate spf and reach "-all")

based on #176 created by rdelaage, with record mismatch spotted by RobSlgm,
thanks!
