This ISO "finally" introduces full Plasma-based DE and semi-GUI installer for HoloISO.

Now, only time you will use a keyboard, is when you're going to type password/hostname and usernames

Installer changelog compared to ISO UPD2:

Ship KDE and Vapor appearance
Ship on-screen keyboard
Check if user is created or not
Check if password is entered for users or not
Check if user matches requirements or not thanks to @wynn1212
Ship only copy-to-RAM options by default for convinience
Implement semi-GUI experience using Zenity dialogs
Non-destructive installation now works with any free capacity of drive, once again thanks to @PIPIPIG233666
linux-neptune-dri kernel is reverted to linux-neptune for up-to-date reasons, as linux-holoiso is the main "more compatibility" kernel for use with random devices
Download timeout disabled for pacstrap and pacman, thus eliminating installation failures
