Avoid wiping local config on update

[ldionmarcil]

Hi, I noticed there was an update to the interactsh web interface earlier today. This resulted in everyone's local config being wiped, including server settings but also all of our tabs were wiped. These tabs contain critical information that we were not expecting to lose. Could you make it so updates don't completely wipe our data? Or perhaps a pop-up asking if we want to update to the new version?

Thanks.
