Nmap aliases plugin

Adds some useful aliases for nmap similar to the profiles in zenmap.

Nmap options are:

-sS - TCP SYN scan
-v - verbose
-T1 - timing of scan. Options are paranoid (0), sneaky (1), polite (2), normal (3), aggressive (4), and insane (5)
-sF - FIN scan (can sneak through non-stateful firewalls)
-PE - ICMP echo discovery probe
-PP - timestamp discovery probe
-PY - SCTP init ping
-g - use given number as source port
-A - enable OS detection, version detection, script scanning, and traceroute (aggressive)
-O - enable OS detection
-sA - TCP ACK scan
-F - fast scan
--script=vulscan - also access vulnerabilities in target

Aliases explained

nmap_open_ports - Scan for open ports on target
nmap_list_interfaces - List all network interfaces on host where the command runs
nmap_slow - Slow scan that avoids to spam the targets logs
nmap_fin - Scan to see if hosts are up with TCP FIN scan
nmap_full - Aggressive full scan that scans all ports, tries to determine OS and service versions
nmap_check_for_firewall - TCP ACK scan to check for firewall existence
nmap_ping_through_firewall - Host discovery with SYN and ACK probes instead of just pings to avoid firewall restrictions
nmap_fast - Fast scan of the top 300 popular ports
nmap_detect_versions - Detects versions of services and OS, runs on all ports
nmap_check_for_vulns - Uses vulscan script to check target services for vulnerabilities
nmap_full_udp - Same as full but via UDP
nmap_traceroute - Try to traceroute using the most common ports
nmap_full_with_scripts - Same as nmap_full but also runs all the scripts
nmap_web_safe_osscan - Little "safer" scan for OS version as connecting to only HTTP and HTTPS ports doesn't look so attacking.
