neovim overhaul (#1)

It is a complete redo of the vim/nvim experience. It's neovim with lua everything
While this was configured this way with a local computer in mind it should be easy to set up and use on a remote machine.

Known Issues:

* Fuzzy finder (this is down to me not having understood properly)
* Harpoon adding paths (again me)
* Need to review the `set.lua` and `remap.lua` for a more uniform approach in nomenclature.

This should see more updates.
