Update Version:

New debugging feature: -@ 11
this triggers a download/run of xiin, which reads and writes to file contents of /sys, and also writes to file
lsusb, lspci, lspci -vv, and the last 200 lines of /var/log/Xorg.0.log which can be helpful for debugging various 
gfx driver issues. Might make the last one optional or from another option, we'll see.

Also removed for detected wifi cards the speed and duplex modes, since they are not applicable for wifi

This will not always work, it detects string wireless, wifi, wi-fi, wlan and if found, doesn't make those lines.

Better than meaningless N/A output I'd say.

Debugger should make it easier, places data in a directory in $HOME./inxi/ and tells user where to find it.
