speed up :LspInstall, :LspUninstall, :LspUninstallAll commands (#175)

- `:LspUninstallAll` now just nukes the entire install directory immediately,
  instead of uninstalling each server one by one. There's also a confirmation
  prompt now.
- `:LspInstall` & `:LspUninstall` now sources its autocompletion directly from
  a Lua table, instead of sourcing the server names from each server module (thus
  avoiding unnecessary `require` calls).
