Update to support troublesome special charcters in Service names

Line 433 in e79098f

$ReturnString = & $ServiceControlCmd.Definition $Arguments

I had to change this to:

            $Command = "$($ServiceControlCmd.Definition) $Arguments"
            $ReturnString = Invoke-Expression $Command

This resolved an issue I had when working with a service that contained square brackets [ ] in the name.
