* Fix port scan. Don't send a new line character when scanning.
* Fix port scanning. Possible infinite loop when all range of ports is busy.
Changed port scanning scheme from random to linear because this is the same faster but more predictable.
* Fix port scan. Don't send a new line character when scanning.
echo -n "" for clarity instead of cat < /dev/null

My system doesn't have xdg-user-dir, and shows the following errors on
startup:
./quickemu: line 828: xdg-user-dir: command not found
mkdir: cannot create directory '': No such file or directory
basename: missing operand
Try 'basename --help' for more information.
Usage
quickemu --vm ubuntu.conf
You can also pass optional parameters
--delete : Delete the disk image.
--display : Select display backend. 'sdl' (default), 'gtk' or 'spice'
--shortcut : Create a desktop shortcut
--snapshot apply <tag> : Apply/restore a snapshot.
--snapshot create <tag> : Create a snapshot.
--snapshot delete <tag> : Delete a snapshot.
--snapshot info : Show disk/snapshot info.
--status-quo : Do not commit any changes to disk/snapshot.
--fullscreen : Starts VM in full screen mode (Ctl+Alt+f to exit)
--screen <screen> : Use specified screen to determine the window size.
--version : Print version
From a quick look it should still function correctly, but better to deal
with this case explicitly.
It's only used to get the PUBLIC, which is optional anyway. If I install
it then it just returns ~, at which point it's set to "" anyway.
I also removed it from the list of "requirements" for this reason.
This also deals with an edge case I happened to notice: "xdg-user-dir
PUBLICSHARE" returns "/home/martin/" on my system, whereas $HOME is
"/home/martin", so the equality check fails. This is arguable a problem
in xdg-user-dir, but better to fix it here. This only deals with a
single slash (multiple slashes is harder in bash), which should be
sufficient.
