Giant commit overhauling the interface to use KDE's Kirigami framework,
which is based on Qt Quick. The logic is all but rewritten, allowing
accounts to be separate from profiles.
Now Astra can bootstrap a new FFXIV it can't find an existing one. It
doesn't even run the installer, but instead extracts the files from the
installer on the fly using unshield. libxiv is now included to handle
this task.
