Fortek's Screenshot Timer

I personally enjoy looking through old screenshots but I'm a clown at remembering to take them. 
So, i made this addon that will take a screenshot every 'X' minutes as long as you're not AFK. 
Very simple to use and very lightweight :-). 

Features:
- Take automatic screenshots at specified time intervals
- Smart AFK detection (won't take screenshots while you're away)
- Subtle sound notification when screenshots are taken
- Saves your interval settings between sessions

Commands:
/st help - Shows all available commands
/st status - Displays current timer status
/st set X - Sets the screenshot interval to X minutes
