Switch to -sn and -Pn as the new preferred synonyms for -sP and -P0.

This establishes a more regular syntax for some options that disable
phases of a scan:
	-n  no reverse DNS
	-Pn no host discovery
	-sn no port scan
Also, the -sP was possibly misleading because the 'P' suggests "ping
scan," when you can now do more than just pinging when you disable port
scanning. For example, -sC -sn and -sn -Pn --traceroute make sense.
