• Adds attack_aliases which allows us to use short names for attacks like "nmap-fast" instead of having to write out nmap -F ...
• Adds --format to gauntlt so you can print out the results in html or json
• Moves to new naming structure and away from the leading 0 in the gem version

Includes dirb and a new option "--allsteps" which lists all available steps to use inside of gauntlt
