Texture Update

Made it possible to change textures/name of the Portal Gun snd Glados Portal  of P-Body and Atlas Guns as a setting in the RP

Also found issues when changing the texture so I recommend to change the texture with the toggle like this 

1. Make a world with the addon
2. Leave the world
3. Go to Resource Packs
4. Go to setting of the Rp of the addon
5. Select the P-Body and Atlas option 
6. Join the world MAKE SURE U DONT GO BACK TO SETTING OF THE RP OR THE SETTING WOULD RESET
7.  Ur done
