Netsuite have changed how sandbox urls work

[perryn]

Sandboxes no longer have a different url, but just use a different account id, and this means the 'sandbox' configuration option no longer works as documented.

(A workaround for using this gem with a sandbox account is to set 'sandbox' to false and append _SB1 to the account id)

@iloveitaly Sure... but there's a lot on my stack atm, so don't wait around for me to get to it if someone else has time :)
