Refactor DOOM init & add new init hooks

+ Add doom-init-hook and doom-post-init-hook to simplify Emacs init
  hooks into less ambiguous ones.
+ Attach former after-init-hook and emacs-startup-hook hooks to new doom
  init hooks.
+ Vastly improves daemon and tty support: preventing incorrect colors
  from bleeding across face class barriers, and into GUI Emacs and vice
  versa, when spawned with emacsclient.
+ Fix persp-mode breaking Emacs daemon, and ensuring that initialization
  is done properly in terminal Emacs (and emacsclient frames).
