provide a "help" command

[mdeous]

Currently, the only way to know available commands is to "tab-tab", which just gives a list of registered commands. For example, I try the show command, I'm told it's supposed to take an argument, but nothing tells me what arguments it expects, tried show modules and show exploits (like in metasploit), but both didn't work, and I still have no idea of what arguments I should give.

A help / help <command> would thus be really useful to know what each command does, and what arguments they expect.

Thanks for the suggestion, I'll add this to the list of things for the next release 👍
