Added PowerShell Scripts into WIP folder

[sid351]

I've added some PowerShell scripts to be used as "Script Checks":

• Win_Disk_Health_Check uses the Storage Reliability Counters instead of WMI classes
• Removed a duplicated Win_Disk_SMART file and renamed the remaining one
• Win_CPU_Uptime_Check for reporting on devices with high uptimes
• Win_RAM_Available_Check for checking the amount, or percentage, of free available RAM (at the time the check runs)
• Win_Battery_Capacity_Check for checking the full charge capacity against the design capacity
