Use Neovim 0.5 nightly

[knowler]

I’ve been seeing some cool Neovim plugins that require the 0.5 nightly, so I am going to try upgrade to it. I also would like to substitute coc.nvim with the built-in LSP. It should be interesting to see if it compares since the former is quite featureful. Also, maybe it works with the new LSP?

TODO:

• Add configs for JSON, CSS, Rust, etc.
• Add LSP shortcuts
• Look for plugins that build on the new LSP feature
• Re-add deoplete Use nvim-completion for autocompletion
• Explore how to use Tree-sitter
• Fix issue with Airline (was fixed on master)
• Figure out auto import declarations
• Figure out linters + formatters
