`ModeChanged` looks like a more reliable way to detect an "exit insert mode" event and is a lot simpler (doesn't need a timer). Also, it can detect some other transitions like `\<C-o\>` in insert mode.
The `ModeChanged` event is available in:
* [Vim 8.2.3430](f1e8876fa2)
* [NeoVim 0.7.0](69bd1e4e36)

Use a repeating timer to emulate InsertLeave mode for users who have not
rebound <C-c> to <Esc>, like many experienced Vim users do. This allows
ALE to start linting when you finish typing by default without having
to know about this quirk in Vim or Neovim.
This commit adds support for renaming symbols in tsserver and with LSP tools, and for organising imports with tsserver. Completion results for symbols that can be imported are now suggested if enabled for tsserver completion done via ALE.
