Fix start.bat (ASCII-only, guaranteed window stays open) + add start.ps1

Browse Source 
- start.bat: remove all Chinese characters (caused silent failure when
  Windows batch parser ran before chcp 65001 took effect); add :error
  label so window stays open with pause on any failure
- start.ps1: PowerShell alternative launcher with coloured output,
  works without worrying about cmd.exe encoding issues
