[FEATURE] Cron/Daily backup

[Kunepro]

As I understand it, tabHamster saves the session when the browser is closed. Problem is that since some years I started working on OSX, and I never shut down the machine, I just put it to sleep. This makes the backups a lot more less frequent (only on updates where a restart is required). I would love for an option where instead I can decide to make the backup daily.

P.S.:I've used tabHamster for years and it saved me from mental breakdown several times.
For this I want to thank onikienko and the other people that worked on this project.
