Particle menu, and copy-and-paste

This is more of a small update.

The particle menu:

The particle menu has be in the simulation but now it shows that possible particles to chose, you can use CTRL+C to copy the text in the menu to you clipboard (You may need to configure the permissions to ask or allow), and you can also use CTRL+V to paste into the menu.

Building:

Another small thing is that you can use the right mouse button to delete the particles, no more switching when your cursor slips!

Small note:

I'm not sure if I'll finish this project, it was fun, but HTML is a huge pain to work with, if people start coming to the simulation I may finish it, but currently, I have been talking to a wall, not fun. So there may be a few more updates before I put this project to the side, maybe head back to MicroStudio to work there when this is finished, I may come back here and there just to try some stuff, or I post a new project on itch.io, but this project is slowing down without a reason to continue. I hope I come back... Well I hope I don't leave, but I don't know.
