Win disk space check

[sid351]

I've updated the script to:

• Fix an issue where it was checking the USED percentage available, and not the FREE percentage available
• Add the ability to optionally log ALL results in case you also want to know exactly how much free space there is
• Condense the logic and only have one area where the output of the check is created
• Renamed with PowerShell approved verbs
• Added descriptions to the parameters so they will appear in Get-Help
• Removed an unused variable
• Filtered out the TEMP drive from the check (hardcoded in the Where-Object)
• Set the Percentage and Amount outputs to be 2 decimal places
• Updated output messages to be more descriptive for clarity
