Currently on a system without xterm or konsole (like fresh
Ubuntu install) the fsck check will not launch. Added
gnome-terminal as an alternative and fixed an issue where
konsole will always error out as --title and --caption are
no longer valid arguments.
Previously the error message was simply "xterm not found", so
new LangString LINUX_EX2MSG_TERMINALNOTFOUND was added to let the
user knows which programs they need to get the feature working.
Removes the options exFAT and Btrfs being shown when creating a
volume in text mode when the system does not support them and will
end up erroring out at the end. Hide Btrfs option when the volume
is too small, as we will anyways fail right after.
Hardcoded numbering changed to dynamic as the available options
are not necessarily consecutive.
