Add xterm.js to D-Installer web interface
an idea by IGonzalezSosa
Having a terminal you can use at installation time, especially while debugging, is pretty handy. With YaST, you can open a terminal anytime (ctrl+alt+shift+x) in the graphical installation. In the case of D-Installer, you need to switch to a TTY (e.g., ctrl+alt+f1) and stop seeing the installation screen. If you are installing remotely (unless you are using VNC in YaST), you must rely on SSH.
