Panel borders are done and working! :D

How annonying was it?

The tricky part was getting the layout constants to line up correctly (it gets pretty annoying if you’re trying to find where you accidentally forgot to add one to a value)
Got there in the end though.

Anything else?

Also cleaned up the repo. I also added a git submodule so that PDCurses actually gets cloned too if you pass the --recurse-submodules when cloning.
Now the foundation is solid and I can actually start on the editor itself next session. :)

I also included a lil preview of how it looks rn :)
