Update tiny11maker.ps1 (Param fix, unique log file with date)

Fixed the Define parameters, moved to the top (if not will print error, param needs to be set at the beginning) 

Also changed the log output from tiny11.log adding date and time, for better troubleshoot, and to avoid file lock or exist from a previous attempt to run the tool.
