Added missing packages for grub (cnchi needs them) and f2fs filesystem. Also put lightdm as greeter, but still need to check the build script to ensure it is configured correctly.
Switched to LightDM; Adjusted aitab in an attempt to created smaller iso; Enabled tap-to-click and two-finger-scroll for touchpads; Added -l parameter when umount is called, though still fails sometimes.
