Don't modify NetworkManager.conf, just stop NetworkManager temporarily 

Seems to fix issues I was having while already connected to a network when starting AP
No longer a need to backup/restore NetworkManager config
We aren't routing traffic to the internet, so no need for iptable modifications
Stop dnsmasq before restarting NetworkManager
