Made checks to avoid reinstalling installed tools.
Fixed working directory
Changed nmap targets to subdomains instead of IP addresses
Enabled nmap's DNS resolution
Used nmap's default stylesheet
Disabled running masscan & nmap in the background. Previously, portscan is running (in the background) in parallel w/ directory bruteforcing. Due to the number of requets being sent by the "dirbrute" tools, portscanning might be inaccurate.
