Added button for ctrl-alt-del

Pressing Ctrl-Alt-Del does work, but it locks the local PC as well. I have no idea how to add a composite button to the source files, but made these changes to the deployed solution:

html file: <button id="ctrlaltdel">Ctrl-Alt-Del</button>

.js file: CtrlAltDel:[336715889,67577015735218289]

.map file: (Is this required?!?) CtrlAltDel: [0x1411E071,0xF014F011E0F071]

All files in "/usr/local/lib/node_modules/pilo/frontend/dist"
