Feature: save domain/address to the password entry

[mbalc]

this feature is inspired by the Android app "Keepass2Android"

whenever you pick a password for a website to log in with, that app asks if you want to store the website data in the password entry notes, so that the app can easily find the password the next time you log in

it's annoying for me that I have to type in the entry name every time I login to a specific internal VPC website I use in my job
