Suggestion: Add hibernate support option

[esemeniuc]

The arch tutorial on hibernate is quite mechanical and could probably be done via scripting to save some effort: https://wiki.archlinux.org/index.php/Power_management/Suspend_and_hibernate#Hibernation

Also using suspend-then-hibernate would help laptop users from draining their batteries and losing work when left alone for a long time: https://wiki.archlinux.org/index.php/Power_management#Hybrid-sleep_on_suspend_or_hibernation_request This involves modifying HandleLidSwitch=suspend to HandleLidSwitch=suspend-then-hibernate in /etc/systemd/logind.conf Details: https://jlk.fjfi.cvut.cz/arch/manpages/man/logind.conf.5 Also discussion about suspend-then-hibernate at the bottom of the page: https://wiki.archlinux.org/index.php/Talk:Power_management/Suspend_and_hibernate#Suspend_then_hibernate
