Fix the detection for NVIDIA driver on graphical installer, this prevents
false-positives from having the driver on the installe rISO
Went through PBI's and pruned any that are deprecated / no longer supported.
Update installer and warden to automatically create the default jail
"template" upon first boot. This will save the user the time downloading
the 100MB+ of dist-files the first time they create a jail, especially
since those dist files are on the ISO already.

Now when creating jails, the only downloads to do are packages, which is much
smaller / faster.
