Add a `.desktop` file so that WM launchers (`dmenu`, `rofi` etc) can easily find a GUI application

This is such a nice tool! I loved using it! It doesn't try to be fancy, but provides as-is apt description and utility as xinput, only in GUI form.

Just a quick [Optional] suggestion:

When I installed it in Arch (I use i3-wm with rofi), rofi didn't put this app inside the Application category since it didn't have any .desktop file associated with it.

I've created one and put it in /usr/share/applications/xinput-gui.desktop. If you include it with your Arch AUR package or other dist packages, GUI launchers would be able to find this easily.
