Log files are not collected if TEMP environment variables are redirected

If a session host's TEMP environment variables have been modified from standard Microsoft-provided values, Nerdio does not respect the change and continues to look for logs in C:\Windows\Temp. Enhance Nerdio to use host environment variables during log collection. As is, log collection actions in Nerdio result in empty zip files becuase Nerdio is attempting to collect files from a location that does not exist.
