Updated to work with Blender 3.6 and fixed some other bugs

[angelo234]

• Compatible with Blender 3.6 and backwards compatible (3.6 allows the user to define multiple addon directories which broke the code)
• Prioritizes downloading Blender from
  • first https://ftp.nluug.nl/pub/graphics/blender/release/Blender
  • then https://builder.blender.org/download/daily
• Fixed using the temp directory to cleanup the addon (at first I removed but added it back later)
• Fixed cleaning pycache files and also considers pycache files in subdirectories
