Add ex 35,36 enums; updated README

I'm changing the order of some more topics. Trying to explain the value
of pointers when we're mostly dealing with stack-sized values like
integers feels convoluted. So I'm starting with enums (which also has a
nice segue from an earlier "switch" exercise). Then structs. Then unions
(just in keeping with the order of these items on ziglearn.org) and THEN
pointers and multi-pointers and slices.
