Support specifying more than one target at the same time

[caribpa]

Due to the fact that the purpose of this tool is automation, it would be a good idea to allow specifying more than one target.

To achieve this, I think that the way the script is called should be modified to the following:

# The -H/--host flag is dropped as flags usually enable optional functionality
$ ./nmapAutomator.sh --type All 10.1.1.1

# So that the following is possible:
$ ./nmapAutomator.sh --type All 10.1.1.1 10.1.1.123

# As well as:
$ ./nmapAutomator.sh --type All 10.1.1.1 academy.htb

nmap recognizes more than one target (and subnets), so extending these capabilities to the base functionality of the script are a good idea.

Yeah i'm planning to add this along with the --remote feature, as in remote scanning you'd first need to find live hosts. I don't want to break legacy support, so i don't want to change the way the script is called.

Instead, i'm planning to add a type called network or something similar, and the script will add /24 for the network nmap scan.

I understand that, I think that simply changing the order of the flags can work for implementing what I'm suggesting without breaking legacy compatibility, so:

$ ./nmapAutomator.sh --type All --host 10.1.1.1

# Instead of
$ ./nmapAutomator.sh --host 10.1.1.1 --type All

And, to top that, the --host flag could be made optional (so compatibility with the older script is there).

I've added this as an upcoming feature, so that we can start working on it. I'm closing the issue to keep the repo clean.
