Default timeout for 'jag scan' with IP address is too low

[kasperl]

It seems pretty common that we cannot complete the HTTP /identify request in 600ms. Perhaps we need a higher default timeout when we're scanning specific addresses because it involves a HTTP roundtrip that isn't necessary when just listening for broadcasted UDP packets?

600ms sounds like a lot of time. I wonder if something else is going wrong.
