(Emacs/config|init)~cut my init time to just a second

I had a problem with after-init-hook which would (while supposedly
keeping (emacs-init-time) under 1.2 seconds) take ages to start emacs
just due to how many things were starting up using it.  So I removed
all the after-init-hook functions and instead aggressively demand the
stuff I need and defer everything else through ":defer", ":after",
":hook" and ":general".

Happy to say my boot time is now actually 1.2 seconds without
compilation.

them. This allows me to search my configuration pretty quickly.
