Support new options

after a quite scan over https://neovim.io/doc/user/news-0.10.html and https://neovim.io/doc/user/deprecated.html#deprecated-0.10, i think it's fine w/ current option setup.

Just took some time to read through the release notes. I think we could possibly implement those changes

- complete: ".,w,b,k" --> ".,w,b,k,kspell"
- completeopt: "menuone,noselect" --> "menuone,noselect,popup"
- smoothscroll: nil --> true
