SoftwareUpdater - add additional buttons for restart
|Reported by:||vidrep||Owned by:||perelandra|
SoftwareUpdater downloads and installs both Haiku core system files and dynamically loaded application and library packages when updating. The Haiku core system files (eg. haiku-hrev1~alpha4_pm_hrev51803-1-x86_64.hpkg) require a system restart before they are usable. After the update(s) are complete, we could have a couple of options, like what is found on other OS updaters; "Restart system now", "Restart later" (maybe with a reminder notification), and "Quit".
