Portal Gun - Reworking in LUA code (Aperture Science Handheld Portal Device)

This is a reworked version of the addon "Portal Gun - Aperture Science Handheld Portal Device" by prynncesslua / Bobblehead.

After numerous re-uploads to fix the old version, I decided to start from scratch by reworking the original addon. It took me days to implement everything and repeatedly test the Portal 1 campaign to fix certain bugs. In the future, I will release regular updates, but if you encounter any bugs or Lua errors, please:

STOP RE-UPLOADING ADDONS TO MAKE A FIXED VERSION OF THEM TO YOUR LINKING.

I would like the This new version will NEVER be re-uploaded or reused for any future add-on projects. Please respect the work of others, and I will have to accept the consequences. Thank you for your understanding.
