Do not log me out for 30 days on this device

Using the admin panel frequently and having phone calls at the same time can be challenging due to the short cookie life you've set for admin panel logins.

It would be fantastic to have an option on the first login that says, 'Do not log me out on this device for 30 days'.

Each time I'm on a long call, I get logged out of any accounts, really tough. :-)

Thanks!

Ben
