[addin] [afk] Create Away From Keyboard add-in

[DamianSuess]

As a user, I want the Away From Keyboard (AFK) mini-app to be incorporated as an add-in. This app makes sure your screensaver doesn't activate and simulates you being at the keyboard

Features:

• Move mouse on interval
• Generic keystroke simulator
• Bound to the window border
• Send keystrokes in our in-app textbox

Already created a standalone test app. Ready to make it an add-in. However, should it be downloadable content or a pre-installed utility?
