Rename scripts for better consistancy (#866)

* Address shellcheck concerns with n2n_gateway.sh script

* Rename n2n_gateway.sh to live with all the other scripts (and update docs)

* Rename hack_fakeautoconf to make it clearly a shell script

* Address shellcheck concerns with hack_fakeautoconf.sh

* Rename python scripts to match other n2n tools

* Fix windows compile - when streamlining the use of hack_fakeautoconf.sh, I forgot to update all uses of this script
