Persistence with schtasks.

This Module will create a schtask that can either run once the user is idle,
or if the user is part of the admin group you can then create schtasks that
can work at boot or user login.  Windows checks a users idle time ever 15 minutes.
This should help keep persistence on a box as a normal user.
I'm getting ```Rex::TimeoutError``` when targeting Windows 2003 SP2 with "EXEC". Is it supposed to work on win 2003 with this technique? Do you have a list of OS versions which should work with this module?
