Added crontab scheduler for jiggler

[jackislanding]

Explanation of fields:

• Schedule
• • Crontab that allows user to set the schedule of when the jiggler is active
• Jitter Percentage
• • Variance to the jiggler schedule.
• • Example: Jiggler is set to fire every 30 seconds. If using a jitter of 50%, this adds +/- 50% of 30 seconds, resulting in a random range from 15 - 45 seconds.
• Inactivity Limit
• • How long the mouse/keyboard can be inactive before the jiggler starts triggering.

Note: The jiggler was broken since the lastUserInput variable was never reset, resulting in the jiggler firing nonstop after 20 seconds. This is now fixed by using the built-in gadget GetLastUserInputTime function.
