Upgrade to 2.8

[matanshukry]

• Convert shadeless/material properties to 2.8 nodes
• combined 2 files into 1 (I have no idea how to run them without
  installing the addon as 2 files; it's just easier. 2nd file is really
  small anyway)
• Added .gitignore with *.blend/1 so I could easily play with my .blend files in the same directory.

Notes:

• I don't really know how it was suppose to work in 2.79 so I don't really know if it's working as intended. However the Create Data button creates the simulation and the simulation seems to work

I suggest you create a 2.8 branch and merge this PR into there, then see if there are any other issues.

Nice, thank you! I'll take a look at it in the next few days.
I've been slacking on updating my addons for 2.8 since I'm still using 2.79 for my current projects and updating my WIP files this far in would add too much time to some already very overdue mods.

I took a look at it, and it's a good start. The addon loads and the panel and calculations work after changing the bl_info version, but sadly, there's still something missing to get it to actually write the values to vertex colors. I'll need to take a look at the API doc and see what changed about vertex colors.

Edit: Never mind, it looks like the panel is missing some things and calculations result in vectors filled with 1s. Still looking into it.
