Multi targ reveal

Hi guys,

Compliments on the scanner so far!

- I felt batch support was something i was missing so I implemented it quickly. 
- Also implemented an option to automatically expand attack surface by all known sites on server (fetched from webservice) to save time and effort when looking for the weakest link the server hosts.

TODO:
+ Implement threading, to speed things up
+ Clean up code, this was just a quick implementation
