Close #4605 - Emulate InsertLeave mode

Browse Source 
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.
