Subject: Add runtime language configuration (#1794) (#1866)

* Add runtime language configuration (#1794)

* Add set-language typable command to change the language of current buffer.
* Add completer for available language options.

* Update set-language to refresh language server as well

* Add language id based config lookup on `syntax::Loader`.
* Add `Document::set_language3` to set programming language based on language
  id.
* Update `Editor::refresh_language_server` to try language detection only if
  language is not already set.

* Remove language detection from Editor::refresh_language_server

* Move document language detection to where the scratch buffer is saved.
* Rename Document::set_language3 to Document::set_language_by_language_id.

* Remove unnecessary clone in completers::language---
